TARGET_CPUTYPE should exist solely in Makefile.inc1, similar to

TARGET_ARCH and TARGET.  This is problematic when one has the =
(unconditional) type of assigment for CPUTYPE in /etc/make.conf.
(This would override what was set on the command line to "make
buildworld".)

Add a (horrible) kludge to Makefile.inc1 to check the type of
assignment for CPUTYPE (only for those who attempts to set it to
a different value).  Fix an example make.conf.  Fix the kernel's
build-tools target (aicasm only at the moment) to catch up with
bsd.cpu.mk,v 1.15 (BOOTSTRAPPING replaced with NO_CPU_CFLAGS in
Makefile.inc1's BMAKE).
