The OSX binary sage-5.0-OSX-64bit-10.6-x86_64-Darwin.dmg dies in MPFR on
Core 2 Duo processors. This is because the MPIR spkg only checks
`SAGE_FAT_BINARY` on Linux systems.

[http://boxen.math.washington.edu/home/jdemeyer/spkg/mpir-2.4.0.p4.spkg]
=== mpir-2.4.0.p4 (Jeroen Demeyer, 18 May 2012) ===
* Trac #12954: when SAGE_FAT_BINARY=yes is specified on a system which
doesn't support --enable-fat, instead build for a generic CPU by
removing all -march= and -mpcu= CFLAGS.
* Disable SAGE_FAT_BINARY when bootstrapping GCC.
* Rename MPIR_EXTRA_OPTS to MPIR_CONFIGURE.
* Add configure options directly to MPIR_CONFIGURE, no longer use
SAGE_CONF_OPTS for this.
* When user specifies CFLAGS, append them to MPIR's flags instead of
completely replacing MPIR's flags.
* Remove $default_cflags and get_processor_specific_cflags().
