I've always been of the opinion that GCC shouldn't install libffi.
There have been some objections in the past.  Maybe I'll try again.

It's been a while since I've looked at EH in the GNU toolchain.  I
believe the -fexceptions would always emit an .eh_frame section, so
this test made sense.  But now it seems that GCC emits these .cfi*
directives, and the assembler is responsible for emitting the
.eh_frames.   If this is true, perhaps we should just scrap the
.eh_frame code all together and use .cfi* assembler directives.  Makes
sense?
