Can somebody debug where the sigill is coming from? Use gdb to narrow down the library? (e.g. sage -f gdb and then run sage -gdb as root on OSX)

I cannot test the 6.9 on my system (without rebooting with disabled security). But the current sage-6.10.beta1-x86_64-Darwin (with md5sum = f5eba161c01c37aa0422519dd4f028d6) also has problems, even though it has presumably been built with SAGE_FAT_BINARY=yes

Program received signal SIGILL, Illegal instruction.
0x000000010ab1e0b0 in __gmpf_set_d ()
from /Volumes/sage-6.10.beta1-x86_64-Darwin/sage/local/lib/libmpir.16.dylib

On my system, I get this from the mpir platform detection code:

el-capitan:mpir-2.7.0 cn$ /bin/sh ./configfsf.guess
x86_64-apple-darwin15.0.0
el-capitan:mpir-2.7.0 cn$ /bin/sh ./config.guess
core2-apple-darwin15.0.0

The first is what's used in SAGE_FAT_BINARY=yes, the 2nd gives a working configuration for me. Maybe we should force configfsf.guess to return "core2" also... ?
