[PATCH] x86-64: Fix for arch/x86_64/pci/Makefile CFLAGS

The arch/x86_64/pci directory was giving problems in a wierd cross-compile
environment.  The exact cause is unknown, but the Makefile used CFLAGS
instead of EXTRA_CFLAGS.  From what I can tell from
Documentation/kbuild/makefiles.txt, CFLAGS should not be used for this, it
should be EXTRA_CFLAGS.  And it solves the cross-compile problem.
