gcc: disable C++ support for Blackfin

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.

          Enable this option if you want your toolchain to support the
          C++ language and you want C++ libraries to be installed on
