Resending patch. It got lost somewhere. Thanks for pushing Ben.

I applied this by hand. Your patch appears to be whitespace damaged. Also, I
expanded the commit message and turned it into,

efi: fix typo in Makefile

commit 9dead5bbb825 ("efi: Build EFI stub with EFI-appropriate options")
contains a typo which means that the efi_stub_$(BITS).o code is still not
compiled with -fshort-wchar and -mno-red-zone.

Fix it with s/KBUILD_CLFAGS/KBUILD_CFLAGS/

I ended up dropping this patch because the following has been applied to -tip,

commit 918708245e92941df16a634dc201b407d12bcd91
Author: Jan Beulich <[email protected]>
Date: Wed Apr 3 15:47:33 2013 +0100

x86: Fix rebuild with EFI_STUB enabled

eboot.o and efi_stub_$(BITS).o didn't get added to "targets", and hence
their .cmd files don't get included by the build machinery, leading to
the files always getting rebuilt.

Rather than adding the two files individually, take the opportunity and
add $(VMLINUX_OBJS) to "targets" instead, thus allowing the assignment
at the top of the file to be shrunk quite a bit.

At the same time, remove a pointless flags override line - the variable
assigned to was misspelled anyway, and the options added are
meaningless for assembly sources.

[ hpa: the patch is not minimal, but I am taking it for -urgent anyway
since the excess impact of the patch seems to be small enough. ]
