Bug 1475566 Disable #pragma comments for MinGW Builds r=glandium

In the MinGW browser build job, we're going to use -fms-extensions,
which will tell clang to start processing these comments. Clang
cannot process them correctly (it's an upstream bug) but it doesn't
need to, because we include the libs we need in moz.build files.

So we exclude them for MinGW builds. mingw-clang gets them wrong and
mingw-gcc (which doesn't even work anymore on -central) ignored them.

In the future, with a llvm fix, we could clean up the moz.build
files and re-enable these comments.
