The SEGV is function_attribute_inlinable_p trying to dereference
a NULL pointer:
=>    for (i = 0; targetm.attribute_table[i].name != NULL; i++)

MMIX (and CRIS, which fails much earlier in libgcc compiling
_divsi3.i) don't have machine attributes, so they don't override
the target-def.h: #define TARGET_ATTRIBUTE_TABLE NULL so
targetm.attribute_table is still NULL.  I predict failures for
mn10300 and mips too.

It's likely due to some attribute change, in particular the
large ChangeLog entry dated:

Neil, can you please have a look?
