Wipe out traditional opt from x86_64 Makefile

Among other things, using -traditional as a gcc option stops us from using macro token pasting, which is a feature we heavily rely on.

There was still a use of -traditional in arch/x86/kernel/Makefile_64, which this patch removes.

I don't see any problems building kernels in my x86_64 box without -traditional.
