I just noticed a similar fix is in upstream, in a new release of Qhull.
Oh well, maybe we'll just upgrade the bundled library.

Although it might still be good to add -fno-strict-aliasing flags to
the compilation, as the upstream cautions that on gcc < 4.4 there might
be problems (although I don't see how they can come from the same source).

I however have no idea how to do this with distutils only for gcc.
