My proposal for the libgcc runtime ABI (ia64 gcc/glibc is broken.)

	On AIX, multilibs select different architecture variants.  These
can make a lot of difference in the performance of the code generated for
DI helper functions based on longlong.h.  It is not clear that forcing
everyone to use the "common-mode" versions of the library for correct EH
behavior is acceptable.
