Hmmm, `gcc` should actually be `$CC`, since we tested the version of the
latter (and would use that one to build GCC anyway).
The `grep` should be ok, although the safest way would probably be to
search for (literally) `multiarch`, which is contained in the configure
options (e.g. `--enable-multiarch`), and/or the command line of `cc1`
(`-imultiarch <system triplet>`).

Can you elaborate in which way GCC 4.6.'''1''' is broken for Sage?
