It allows A Way.
Of course you should fix make(1) to support the POSIX way if this is
not too hard. If make can see .POSIX before including sys.mk, then
it could alternatively include a POSIX-sys.mk instead. This would be
cleaner than the ifdefs in sys.mk, and would inhibit breakage of the
POSIX case by putting things like CTF in its rules.
