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. -- Joseph S.
