I'm packaging a library that does some heavy mathematical

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.
