Well, we don't want any local changes to config.* in GCC / binutils-gdb /
glibc - those files should remain as files that only get updated by
verbatim copying from config.git.
In glibc, sysdeps/x86_64/preconfigure.ac already checks for x32. I think
it would be fine to combine sysdeps/i386/preconfigure and
sysdeps/x86_64/preconfigure.ac into a single sysdeps/x86/preconfigure.ac
that allows both i?86 and x86_64 triplets to be used for all three ABIs,
determining the correct machine and base_machine settings based on how the
compiler behaves.
