x86: do not use $(ARCH) when not needed
For x86 ARCH may say i386 or x86_64 and soon x86. Rely on CONFIG_X64_32 to select between 32/64 or just hardcode the value as appropriate. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Ingo Molnar <mingo@redhat.com> Cc: "H. Peter Anvin" <hpa@zytor.com>
