Subject: [PATCH] kbuild: add arch/$ARCH/include to search path

This patch conclude the support for

   arch/$ARCH/include

Note: The individual architectures will most likely require
      a few minor patches to support locating header files in
      arch/$ARCH/include

Testing shows that it worked out-of-the-box for sparc.
x86 required a few trivial changes in the arch
specific Makefile and a few include paths had to be adjusted.
