Fix 'broken' ifdefs.
icc does not support profiling yet so remove unfinished code which was
supposed to help.

Intel C/C++ compiler (lang/icc) to build the kernel.
The icc CPUTYPE CFLAGS use icc v7 syntax, icc v8 moans about them, but
doesn't abort. They also produce CPU specific code (new instructions
of the CPU, not only CPU specific scheduling), so if you get coredumps
with signal 4 (SIGILL, illegal instruction) you've used the wrong
CPUTYPE.
Incarnations of this patch survive gcc compiles and my make universe.
I use it on my desktop.
To use it update share/mk, add
/usr/local/intel/compiler70/ia32/bin (icc v7, works)
or
/usr/local/intel_cc_80/bin (icc v8, doesn't work)
to your PATH, make sure you have a new kernel compile directory
(e.g. MYKERNEL_icc) and run
CFLAGS="-O2 -ip" CC=icc make depend
CFLAGS="-O2 -ip" CC=icc make
in it.
Don't compile with -ipo, the build infrastructure uses ld directly to
link the kernel and the modules, but -ipo needs the link step to be
performed with Intel's linker.
Problems with icc v8:
- panic: npx0 cannot be emulated on an SMP system
- UP: first start of /bin/sh results in a FP exception

This is known to fix compilation of s_log1p.o in lib/msun on i386,
as otherwise it attempted to use s_log1p.S as the source (which is
marked broken) instead of legal s_log1p.c which is in CFLAGS. The
normal case where .depend file exists is not affected.

as it was decided that our toolchain will revert to looking
for libraries in /usr/lib only.
- Make /usr/lib/libfoo.so -> /lib/libfoo.so.X symlinks absolute
so that they still work if /usr is symlinked.
- Remove stale /usr/lib/libfoo.so.X libraries during install.

hose your system. You end up with just about everything statically linked
(except for libpam.so), which then causes all the pam users to fail.
eg: login, sshd, su etc all stop working because dlopen no longer works
because there is no libc.so in memory anymore.
gcc passes -L/usr/lib to ld. The /usr/lib/libxxx.so symlink is *not* a
compatability link. It is actually the primary link. There should be no
symlinks in /lib at all. Only /lib/libXX.so.Y.

Note no libc.so.5. Hence libpam.so.2 has unresolved dependencies.
I believe this is also the cause of the recent buildworld failures when
pam_krb5.so references -lcrypto stuff etc and when librpcsvc.so references
des_setparity() etc.
This change could not possibly have worked, unless there are other missing
changes to the gcc configuration. It won't work with ports versions of
gcc either.
are created in the correct location. Always make them. For libraries
that live in /lib, this causes a /lib/libfoo.so and a compatibility
/usr/lib/libfoo.so to be created. We may want to drop the
/usr/lib/libfoo.so symlink at some future point.
need relative pathing to work correctly. This is s necessary step
for putting libraries in /lib while the .so symlinks still live
in /usr/lib.
This should be a big NOOP in the case where SHLIBDIR == LIBDIR.
All .s files that need cpp(1) processing (see gcc(1) manpage's
DESCRIPTION section) have been repo-copied to .S files. This
is mostly to bring bsd.lib.mk in agreement with sys.mk.

symbols from object files has bitrotted over the last
thirteen years, and it now does more harm than good.
An attempt to work around the problems caused by using
ld(1) for stripping was to pass LDFLAGS to the ld(1)
command, but this was not right either as ${LDFLAGS}
should, by design, be used with cc(1) and not ld(1).
One of the proposed solutions was to use the objcopy(1)
utility to do the strip work, and the other would be to
use strip(1), but Bruce Evans suggested not stripping
any symbols at all. This works by leaving the grunt
work to the final strip(1) command (when installing the
binary).

it gets the job done for the /rescue case.

o Make it possible to prevent parts of the tree from being linted
(say) during a 'make world' by setting NOLINT in a leaf Makefile.
o Make "make lint" work (better) for executable programs.
o Clean up (nuke!) a syntax damaged pipeline.
under way to move the remnants of the a.out toolchain to ports. As the
comment in src/Makefile said, this stuff is deprecated and one should not
expect this to remain beyond 4.0-REL. It has already lasted WAY beyond
that.
Notable exceptions:
gcc - I have not touched the a.out generation stuff there.
ldd/ldconfig - still have some code to interface with a.out rtld.
old as/ld/etc - I have not removed these yet, pending their move to ports.
some includes - necessary for ldd/ldconfig for now.
Tested on: i386 (extensively), alpha
directives to ensure that all realinstall sub-tasks are executed
after beforeinstall, similarly ensure that all afterinstall sub-
tasks are executed after realinstall. Demonstration:
all: task1 task2
.ORDER: task1 task2
task2: task2_subtask
.ORDER: task1 task2_subtask
task1 task2 task2_subtask:
@sleep `jot -r 1 0 1.0`
@echo ${.TARGET}
Without the second .ORDER directive, task2_subtask can be run in
parallel with task1.

same set of features as in recently added bsd.incs.mk
(FILESGROUPS, accessibility from both bsd.prog.mk and
bsd.lib.mk, de-pessimized typical installation path,
etc.) New standard targets: buildfiles, installfiles,
and files (buildfiles + installfiles).
Rename `incsinstall' to `installincludes'.
Make `includes' a -j safe shortcut for `buildincludes' + `installincludes'.
`buildincludes' and `installincludes' are SUBDIR friendly, if run directly.
Get rid of the INTERNALSTATICLIB knob and just use plain INTERNALLIB.
INTERNALLIB now means to build static library only and don't install
anything. Added a NOINSTALLLIB knob for libpam/modules. To not
build any library at all, just do not set LIB.
via INCS. Implemented INCSLINKS (equivalent to SYMLINKS) to
handle symlinking include files. Allow for multiple groups of
include files to be installed, with the powerful INCSGROUPS knob.
Documentation to follow.
Added standard `includes' and `incsinstall' targets, use them
in Makefile.inc1. Headers from the following makefiles were
not installed before (during `includes' in Makefile.inc1):
kerberos5/lib/libtelnet/Makefile
lib/libbz2/Makefile
lib/libdevinfo/Makefile
lib/libform/Makefile
lib/libisc/Makefile
lib/libmenu/Makefile
lib/libmilter/Makefile
lib/libpanel/Makefile
Replaced all `beforeinstall' targets for installing includes
with the INCS stuff.
Renamed INCDIR to INCSDIR, for consistency with FILES and SCRIPTS,
and for compatibility with NetBSD. Similarly for INCOWN, INCGRP,
and INCMODE.
Consistently use INCLUDEDIR instead of /usr/include.
gnu/lib/libstdc++/Makefile and gnu/lib/libsupc++/Makefile changes
were only lightly tested due to the missing contrib/libstdc++-v3.
I fully tested the pre-WIP_GCC31 version of this patch with the
contrib/libstdc++.295 stuff.
These changes have been tested on i386 with the -DNO_WERROR "make
world" and "make release".
