Partition the header include path flags into two sets, one for kernelspace
builds and one for userspace builds.
Add the following directories to build after the ordinary include directories
so that #include will pick up the UAPI header directly if the kernel header
has been moved there.
The userspace set (represented by the USERINCLUDE make variable) contains:
-I $(srctree)/arch/$(hdr-arch)/include/uapi
-I arch/$(hdr-arch)/include/generated/uapi
-I $(srctree)/include/uapi
-I include/generated/uapi
-include $(srctree)/include/linux/kconfig.h
and the kernelspace set (represented by the LINUXINCLUDE make variable)
contains:
-I $(srctree)/arch/$(hdr-arch)/include
-I arch/$(hdr-arch)/include/generated
-I $(srctree)/include
-I include --- if not building in the source tree
plus everything in the USERINCLUDE set.
Then use USERINCLUDE in building the x86 boot code.

We have had a number of cases where <asm/cpufeature.h> (and its
predecessors) have diverged substantially from the names list in
/proc/cpuinfo. This patch generates the latter from the former.
It retains the option for explicitly overriding the strings, but by
making that require a separate action it should at least be less
likely to happen.
It would be good to do a future pass and rename strings that are
gratuituously different in the kernel (/proc/cpuinfo is a userspace
interface and must remain constant.)
