i think CPUFLAGS is the thing we want for _end users_ to compile
with their specific cpus flags.

netbsd build only sets CPUFLAGS when it's building a cpu specific
thing for code expecting that (eg, "-marm" for a bunch of the
arm boot programs.)

you should be able to set CPUFLAGS in mk.conf _or_ build.sh -V.
