[Buildroot] [RFCv1 4/8] gcc: musl patches only available for gcc 4.7+

For the moment, the musl support is not in mainline gcc, so it
requires a few patches. We have integrated those patches only for gcc
4.7 and gcc 4.8 at the moment, so only allow those gcc versions when
the musl library is selected.
