Marcel Moolenaar d911f786ab Limit testing for an up-to-date version of make(1) to the world and
buildworld targets by default, but allow it to be done for all user
targets by introducing a boolean option, named ALWAYS_CHECK_MAKE.

This change is by no means perfect and I don't even want to claim
this to be a solution. It does however address the fact that not
everybody likes to see make(1) rebuilt simply because the regression
test failed for some reason or other, including pilot error. It
therefore serves the purpose of keeping the crowd happy until we
have something better or simply reached a compromise.

The reasons for changing the default behaviour are:
o  It avoids a negative, possibly non-intuitive option,
o  It's according to POLA and fond of feet,
o  Only buildworld is documented to do its best to be
   successful at reasonably cost.

# $FreeBSD$
#
# The user-driven targets are:
#
# universe - *Really* build *everything* (buildworld and
# all kernels on all architectures).
# buildworld - Rebuild *everything*, including glue to help do
# upgrades.
# installworld - Install everything built by "buildworld".
# world - buildworld + installworld.
# 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.
# update - Convenient way to update your source tree (cvs).
# most - Build user commands, no libraries or include files.
# installmost - Install user commands, no libraries or include files.
#
# 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.
#
# The user-driven targets (as listed above) are implemented in Makefile.inc1.
#
# If you want to build your system from source be sure that /usr/obj has
# at least 400MB of diskspace available.
#
# 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. `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).
# 5. `reboot' (in single user mode: boot -s from the loader prompt).
# 6. `mergemaster -p'
# 7. `make installworld'
# 8. `mergemaster'
# 9. `reboot'
#
# See src/UPDATING `COMMON ITEMS' for more complete information.
#
# If TARGET_ARCH=arch (e.g. ia64, sparc64, ...) is specified you can
# cross build world for other architectures 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.
