U-Boot supports clang, but it's not as well tested as other things.
However, this patch is still wrong as we do not want to try and force
flags to gcc, just like we don't with the kernel.  For more on U-Boot,
see doc/README.clang (And then possibly do some fixups, I'm not having
super luck with it right now, but I'm in a bit of a rush right now).
