Subject: [PATCH] Makefile: do not create a symbolic link to
 arch/${ARCH}/include/asm

In-tree build:
  - Do not create a symbolic link
      from include/asm to arch/${ARCH}/include/asm
  - Add ${SRCTREE}/arch/arm/include into the header search path

Out-of-tree build:
  - Do not create a directory ${OBJTREE}/include2
  - Do not create a symbolic link
      from ${OBJTREE}/include2/asm to ${SRCTREE}/arch/${ARCH}/include/asm
  - Add ${SRCTREE}/arch/arm/include into the header search path

Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
