Subject: - Define NO_CPU_CFLAGS during BMAKE and TMAKE (and thus XMAKE) so
 that   bsd.cpu.mk doesn't have to worry about compilers other than the
 current   version. - Allow TARGET_CPUTYPE to override CPUTYPE in bsd.cpu.mk.
 - Treat an empty CPUTYPE the same as an undefined CPUTYPE. - For buildworld,
 buildkernel, etc., define TARGET_CPUTYPE to CPUTYPE for   native builds and
 define it to be empty for cross-builds.   TARGET_CPUTYPE is only defined if
 it is not already defined via the   commandline or environment.
