I'd like to get an aarch64 version of this target function into GCC 9.*
too in order to support ILP32/LP64 on aarch64.  It doesn't necessarily
have to be part of this patch though, I could submit one later if you
do not want to add it here.

Aarch64 ILP32 support is in GCC and binutils but not GLIBC (except on a
branch), I am thinking the Aarch64 version of this function would
return "aarch64" or "aarch64_ilp32".  Perhaps we should also have
"aarch64_be" and "aarch64_be_ilp32" for big endian ABI's?
