 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.
