    Hi,

    on ppc64, Thunderbird currently fails to build from source [1] due to an upstream bug in the PowerPC backend in LLVM [2].

    Could you override CC and CXX so Thunderbird is built with GCC instead of
    Clang for the time being?

    Thanks,

    Attaching an updating patch. We actually need to export CC and CXX so all parts of the build make use of gcc and g++. This requires an additional patch which fixes an old keyword in moz.build for skia (see attached).
