Comment (by jdemeyer):
Replying to [comment:11 vbraun]:
> `SAGE_FAT_BINARY` should be synonymous with `SAGE_GENERIC_BINARY`,
though for historical reasons it isn't named well. From
http://www.sagemath.org/doc/installation/source.html:
>
> SAGE_FAT_BINARY - to prepare a binary distribution that will run on the
widest range of target machines, set this variable to "yes"
>
> I think right now you don't remove advanced `CFLAGS` on linux platfroms
if `SAGE_FAT_BINARY` is set.
MPIR actually does support "fat binaries" in the true sense on x86
systems: building a library with code for different processors,
determining at run-time which one to use.
