In general, or for x86? I don't see why we can't just change gcc to
default to -march=i486, and let that be that. Users that get compilers
from distributors need not worry; distributors have the responsibility
for adding a mutlilib, or changing the default, if necessary. Users
that build from source presumably have some ability to muck about with
configury nowadays; otherwise, they'd download binaries.

Well, Ian argued that specifying multilibs at configure time might
amount to writing your own -t file, and then telling configure about it.
