[RFA] Fallback unsupported languages to "minimal"

Now that we have the "minimal" language, we can change the DWARF2 reader
to fallback to this language, instead of using the "unknown" one.

See http://sources.redhat.com/ml/gdb-patches/2003-04/msg00112.html for
more details.

        * set_cu_language: Set the language to "minimal" if the language
        of the CU is not currently supported by GDB.

Seems kind of obvious, but it never hurts to ask. Ok to apply?
