Thanks, Kris. I suspected that either you or markm would
have already tackled the job.

I'm not fluent in FSF configure scripts, but it looks like
configure tests the compiler for specific features to determine
CPU type. The gross hack would be to add CPU_TYPE="generic"
to /etc/defaults/make.conf, and allow users to define CPU_TYPE
in /etc/make.conf. It appears that for example CPU_TYPE="alpha"
is insufficient because each cpu type 21064, 21164, 21264 has
tuned asm code. The bmake file would then have a cascade of
#ifdef CPU_TYPE to pull in the right code.
Would a CPU_TYPE variable be useful for others parts of "make world"?
