What package are we talking about?
There is already at least one package in Fedora which does a similar
thing: ATLAS. It normally automatically tunes itself for the optimal
build flags, so some special tricks have to be done for packaging.
ATLAS has currently the following versions on Fedora:
i686: plain, 3dnow, sse, sse2 and sse3
x86_64: plain and sse2
The plain stands for the "atlas" package. I don't know what flags it
uses.
I"m trying to update the m4ri package, which now does such tricks.
Thanks for the pointer. I'll look at the atlas spec file and see how
it's done there.
