Please no: alpha went this route, and the consequence is that your
self-built gcc will generate code for the build system. This breaks
completely if you have a heterogeneous collection of systems, and the
GCC build system isn't the least common denominator of them. This
single-system mindset creates unnecessary trouble in this scenario.
GCC's configure has enough control over the default target CPU, even
without messing with config.guess, and most other programs won't care
about this at all.
