From: Matt Fleming <matt.flem...@intel.com>
The hostprogs need access to the CONFIG_* symbols found in
include/generated/autoconf.h. commit abbf1590 ("UAPI: Partition the
header include path sets and add uapi/ header directories") replaced
$(LINUXINCLUDE) with $(USERINCLUDE) which doesn't contain the
necessary include paths.
This has the undesirable effect of breaking the EFI boot stub because
the #ifdef CONFIG_EFI_STUB code in arch/x86/boot/tools/build.c is
never compiled.
It should also be noted that because $(USERINCLUDE) isn't exported by
the top-level Makefile it's actually empty in arch/x86/boot/Makefile.

Linus, I expected this fix to go through -tip but Ingo explained that
the offending commit (abbf1590) doesn't exist in -tip yet, which is
why I'm sending this directly to you.
