[Buildroot] [git commit] gcc: disable C++ support for Blackfin

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=9ca80d92e06694241fca95ed85f1883dd0f500c7
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

As discussed with Waldemar, the C++ support for Blackfin is currently
broken, and we don't have a fix in sight for the 2016.08
release. Therefore, this commit disables C++ support entirely on the
Blackfin architecture in the internal toolchain backend.

This will avoid a significant number of Blackfin build failures, that
occur when building C++ packages.
