Marcel Moolenaar 0815243c39 Add support for bmake. This includes:
1.  Don't do upgrade_checks when using bmake. As long as we have WITH_BMAKE,
    there's a bootstrap complication in ths respect. Avoid it. Make the
    necessary changes to have upgrade_checks work wth bmake anyway.
2.  Remove the use of -E. It's not needed in our build because we use ?= for
    the respective variables, which means that we'll take the environment
    value (if any) anyway.
3.  Properly declare phony targets as phony as bmake is a lot smarter (and
    thus agressive) about build avoidance.
4.  Make sure CLEANFILES is complete and use it on .NOPATH. bmake is a lot
    smarter about build avoidance and should not find files we generate in
    the source tree. We should not have files in the repository we want to
    generate, but this is an easier way to cross this hurdle.
5.  Have behavior under bmake the same as it is under make with respect to
    halting when sub-commands fail. Add "set -e" to compound commands so
    that bmake is informed when sub-commands fail.
6.  Make sure crunchgen uses the same make as the rest of the build. This
    is important when the make utility isn't called make (but bmake for
    example).
7.  While here, add support for using MAKEOBJDIR to set the object tree
    location. It's the second alternative bmake looks for when determining
    the actual object directory (= .OBJDIR).

#
# $FreeBSD$
#
# The user-driven targets are:
#
# universe - *Really* build *everything* (buildworld and
# all kernels on all architectures).
# tinderbox - Same as universe, but presents a list of failed build
# targets and exits with an error if there were any.
# buildworld - Rebuild *everything*, including glue to help do
# upgrades.
# installworld - Install everything built by "buildworld".
# world - buildworld + installworld, no kernel.
# buildkernel - Rebuild the kernel and the kernel-modules.
# installkernel - Install the kernel and the kernel-modules.
# installkernel.debug
# reinstallkernel - Reinstall the kernel and the kernel-modules.
# reinstallkernel.debug
# kernel - buildkernel + installkernel.
# kernel-toolchain - Builds the subset of world necessary to build a kernel
# kernel-toolchains - Build kernel-toolchain for all universe targets.
# doxygen - Build API documentation of the kernel, needs doxygen.
# update - Convenient way to update your source tree(s).
# check-old - List obsolete directories/files/libraries.
# check-old-dirs - List obsolete directories.
# check-old-files - List obsolete files.
# check-old-libs - List obsolete libraries.
# delete-old - Delete obsolete directories/files.
# delete-old-dirs - Delete obsolete directories.
# delete-old-files - Delete obsolete files.
# delete-old-libs - Delete obsolete libraries.
# targets - Print a list of supported TARGET/TARGET_ARCH pairs
# for world and kernel targets.
# toolchains - Build a toolchain for all world and kernel targets.
#
# This makefile is simple by design. The FreeBSD make automatically reads
# the /usr/share/mk/sys.mk unless the -m argument is specified on the
# command line. By keeping this makefile simple, it doesn't matter too
# much how different the installed mk files are from those in the source
# tree. This makefile executes a child make process, forcing it to use
# the mk files from the source tree which are supposed to DTRT.
#
# Most of the user-driven targets (as listed above) are implemented in
# Makefile.inc1. The exceptions are universe, tinderbox and targets.
#
# If you want to build your system from source be sure that /usr/obj has
# at least 1GB of diskspace available. A complete 'universe' build requires
# about 15GB of space.
#
# For individuals wanting to build from the sources currently on their
# system, the simple instructions are:
#
# 1. `cd /usr/src' (or to the directory containing your source tree).
# 2. Define `HISTORICAL_MAKE_WORLD' variable (see README).
# 3. `make world'
#
# For individuals wanting to upgrade their sources (even if only a
# delta of a few days):
#
# 1. `cd /usr/src' (or to the directory containing your source tree).
# 2. `make buildworld'
# 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC).
# 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC).
# [steps 3. & 4. can be combined by using the "kernel" target]
# 5. `reboot' (in single user mode: boot -s from the loader prompt).
# 6. `mergemaster -p'
# 7. `make installworld'
# 8. `make delete-old'
# 9. `mergemaster' (you may wish to use -i, along with -U or -F).
# 10. `reboot'
# 11. `make delete-old-libs' (in case no 3rd party program uses them anymore)
#
# See src/UPDATING `COMMON ITEMS' for more complete information.
#
# If TARGET=machine (e.g. ia64, sparc64, ...) is specified you can
# cross build world for other machine types using the buildworld target,
# and once the world is built you can cross build a kernel using the
# buildkernel target.
#
# Define the user-driven targets. These are listed here in alphabetical
# order, but that's not important.
#
# Targets that begin with underscore are internal targets intended for
# developer convenience only. They are intentionally not documented and
# completely subject to change without notice.
#
# For more information, see the build(7) manual page.
