x86: move i386 and x86_64 Makefiles to arch/x86
Sam Ravnborg [Thu, 25 Oct 2007 17:42:04 +0000 (19:42 +0200)]
Moving the ARCH specific Makefiles for i386 and x86_64
required a litle bit tweaking in the top-lvel Makefile.

SRCARCH is now set in the top-level Makefile
because we need this info to include the correct
arch Makefile.
