Subject: kbuild: add arch/$ARCH/include to search path
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5e4786f75d885dd1a5f9fe12f3385ece7656b0c9;p=openwrt%2Fstaging%2Fblogic.git

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.
