x86: unification of arch/x86/Makefiles
Unify the 32 and 64 bit specific Makefiles. The unification was simplest to do in one step although the readability of the patch suffers a bit from this. Noteworthy remarks on the unification: - The 64 bit cpu stuff should be moved to Makefile_32.cpu but I did not feel confident doing it due to subtle differences - The use of cflags-y were abandoned since we have seen one bug where we did wrong due to missing assignment to KBUILD_CFLAGS. The cc-option marcro uses KBUILD_CFLAGS. - The "No need to remake" line are deleted. It caused "make -B" to fail - For 64 bit the sub architecture stuff is not used. - The way head64.o is specified could be nicer - but it awaits the introduction of head32.o (which seems like a win to introduce for readability) - Patch is checkpatch clean Patch is tested by doing a defconfig build for i386 and x86_64 and in both cases monitoring that only relevant files were recompiled when applying the patch.
