This patch is taken from the arch/sparc64/Makefile almost verbatim. It is really only useful when one is running a pure 32-bit userland (using the powerpc toolchain instead of the powerpc64 one) under a 64-bit kernel. It just checks to make sure that the native CC can use -m64 and if it can't resets CC to the powerpc64 gcc.<BR>
