Add a -Bforcedynamic option which generates a dynamic object even
if no shared libraries were given in the link.
Make RRS in text section warnings conditional on "-assert pure-text"
so that I can link non-PIC kernel modules without tons of link

Fix a couple of bugs exposed by the fact that the kernel is not
linked at zero.

Supply 0 for unavailable registers instead of punning the tss to

in it. (The registers are in the pcb; there is nothing interesting
in the tss. This should change someday. At least for dumps, all
the registers should be saved, and common_tss is a good place to
put them.)

ld-specific flags. LDFLAGS is really for ld-related flags for cc,
not for ld, and some flags, e.g., -Bshareable, mean completely
different things to cc and ld. Having the wrong things in LDFLAGS
also broke the standard ${PROG} target. This was kludged around
by using a special rule that depended on LDFLAGS being bogus.
Fixing `make depend' broke the special rule but fixed the standard
rule (except in the DESTDIR case, which was handled more strictly
here than elsewhere).
dependency on `bar' is very unlikely to be correct.
This is a quick fix for broken dependencies in gdb and many other
places. The dependencies on internal libraries are now missing
instead of wrong when `make depend' is run before the libraries
are created.

UPAGES layout.. it was entirely too comfortable with reading and writing
the U area before. I've changed it to use PT_GETREGS/PT_PUTREGS
ptrace ops instead of READ_U etc. The code to read the registers from
core dumps is a bandaid at best. It seems to have problems reading
core dumps from dynamic linked executables still, but at least static
dumps work.

of binutils. For all architectures and object file formats,
".p2align n" aligns to the next multiple of 2**n. Thus for FreeBSD,
it does exactly the same thing as the traditional ".align".
The old ".align" directive has different meanings in different
object formats, and even in different variants of a.out. Sometimes
is aligns to a multiple of n, and other times it aligns to a multiple
of 2**n. ".p2align" is preferable for use in assembly language
sources, since it makes them more portable to object formats other
than a.out.

Don't use the private version of strerror() either.
Use INTERNALLIB and INTERNALSTATICLIB instead of a private install

INTERNALLIB was previously only used in compatibility libraries
(libgnumalloc etc.) and INTERNALSTATICLIB was previously unused.
INTERNAL*LIB probably should be replaced by something like NOSTATICO
together with NO{STATICO,PROFILE,PIC}INSTALL.

2.2 candidate
library with a shared object dependency that contained alias symbols,
the linker incorrectly counted the number of symbols that would be
written, resulting in a fatal internal error. Since our libc now
contains some alias symbols (in "net/res_stubs.c"), this was
sufficient to tickle the bug: "ld -Bshareable foo.so -lc". To
fix it, I moved the accounting of alias symbols to a later point
in the processing, where it is possible to count only those symbols
that will actually be written to the output file.
This fix is well-confined to affect alias symbols only. I have
tested it with a full "make world". I am going to merge it into
-2.2 after a few more days of living with it in -current.
If it is set to a nonempty string, then simply skip any missing
shared libraries. This came up in a discussion long ago as a
potentially useful feature at sysinstall time. For example, an
X11 utility could be used without the X libraries being present,
provided the utility had a mode in which no X functions were actually
called.

nonempty string, then function calls are relocated at program start-up
rather than lazily. This variable is standard on Sun and SVR4 systems.
The dlopen() function now supports both lazy and immediate binding, as
determined by its "mode" argument, which can be either 1 (RTLD_LAZY) or
2 (RTLD_NOW). I will add defines of these symbols to <dlfcn.h> as soon
as I've done a little more checking to make sure they won't cause
collisions or bootstrapping problems that would break "make world".
The "LD_*" environment variables which alter dynamic linker behavior are
now treated as unset if they are set to the empty string. This agrees
with the standard SVR4 conventions for the dynamic linker.
Add a work-around for programs compiled with certain buggy versions of
crt0.o. The buggy versions failed to set the "crt_ldso" member of the
interface structure. This caused certain error messages from the
dynamic linker to begin with "(null)" instead of the pathname of the
dynamic linker.
