Based on inputs from various people I have now updated the patch.
A proper serie with a few preparational patches will be posted
and they are aiming for kbuild-next.

The patchset:

      kbuild: refactor headers_* targets in Makefile
      kbuild: always unifdef files in headers_install*
      kbuild: drop support of ALTARCH for headers_*
      kbuild: code refactoring in Makefile.headerinst
      kbuild: error out early in make headers_install
      kbuild: optimize headers_* targets

The meat of the patch is in the last patch which contains all
the real improvements.
