The point of adding that flag was to create byte-for-byte identical compiler binaries. Have you verified that hacking on T_CFLAGS (instead of XCFLAGS) actually does this? If it doesn't, then I'd say get rid of this (and resign ourselves to not having byte-for-byte identical compilers between the bootstrap and non-bootstrap builds). Don't play with more undocumented flags just to get something that looks like what we had before, if it doesn't actually do what we need...
