whether clang can handle the input file type, and for non-Darwin toolchains it
will invoke gcc for things it cannot handle. For Darwin toolchains, the

layer, and if you happened to enable it (by being on Android or GCC 4.7
platform), you couldn't *disable* it, because there was no 'no' variant.

disable the flag, or pass the positive variant to clang itself to enable
the flag.
