[PATCH] x86_64: Don't define string functions to builtin
gcc should handle this anyways, and it causes problems when sprintf is turned into strcpy by gcc behind our backs and the C fallback version of strcpy is actually defining __builtin_strcpy Then drop -ffreestanding from the main Makefile because it isn't needed anymore and implies -fno-builtin, which is wrong now. (it was only added for x86-64, so dropping it should be safe) Noticed by Roman Zippel Cc: Roman Zippel <zippel@linux-m68k.org> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
