I redid this and ended up with 5 small patches.

Sam Ravnborg (5):
      kbuild: prepare headers_* for arch/$ARCH/include
      kbuild: include/asm may be a file - fix mrproper for this
      kbuild: support arch/$ARCH/include for tags, cscope
      kbuild: asm symlink support for arch/$ARCH/include
      kbuild: add arch/$ARCH/include to search path

This patchset is tested a more than
the previous one and is now also pushed out
to kbuild-next.git so it will apprear in -next shortly.

There were a few bugs around the symlink handling
and make tags is now also functional.
So I consider this ready for merging.

Any comments are welcome!
Patches will follow as reply to this one, but they
are only sent to kbuild and lkml.
