I'm just now in the process of upgrading my own pkgsrc.  Fortunately,
perhaps, I hit a bunch of snags so I haven't gotten much of anything
done yet.  Question is, are there other packages like mplayer where
the "build is nolonger optimized for the build host?"  If so, is there
a generic way of optimizing for the build host for all packages?

I'd really like to try something like "submodel optimization" of kernels
for some of my older hardware.  How do you pass flags like "-O3 -march=k6-2"
to the compiler, and how would I know what value is right for what machine?
Haven't any idea what docs I should be looking for.  TIA!
