Simon J. Gerraty 4234b97720 Fix bug in universe where if upgrade_checks wants a new make,
it gets built 16 times in parallel in the same location.
While we are at it, until we finish getting rid of fmake,
be explicit about the make we want to use, thus avoid the problem
of the temp make being the wrong version.

# $FreeBSD$
#
# 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.
#
# "quick" way to test all kernel builds:
# _jflag=`sysctl -n hw.ncpu`
# _jflag=$(($_jflag * 2))
# [ $_jflag -gt 12 ] && _jflag=12
# make universe -DMAKE_JUST_KERNELS JFLAG=-j${_jflag}
#
# 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. `mergemaster' (you may wish to use -i, along with -U or -F).
# 9. `make delete-old'
# 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.
