Can we not just patch gcc to fix the ice?  That seems like it would be
the best answer.

If that's difficult for some reason, and downgrading gcc isn't an option
either for whatever reason, then it seems like the right thing is going
to be to get mesa-xlib's do_configure() to sort it out.

I'm not sure that anonymous python is going to work since there is no
particularly good and reliable method of determining ahead of time what
version of gcc is going to end up being used for the build.
