[Buildroot] [git commit] toolchain/buildroot: not available for a few mips cores

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=6eaa6460bad197daf1d8d3318aff8e187fe36301
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Commit 1b974425 (MIPS: add support for M6201 cores) explained that the
new core was not supported by upstream gcc, and as of gcc-8-trunk
that's still the case.

Ditto for 3cfbeb83 (MIPS: add support for P6600 cores).

This means that we currently allow to build an internal tolchain for
those cores, yet we have no suitable gcc version.

Disable the internal backend in this case.
