Subject: [PATCH 1/2] ARM: at91: remove unused duplicated filechk_offsets

The filechk_offsets in arch/arm/mach-at91/Makefile is never
used because it is always overridden by the equivalent one in
scripts/Makefile.lib

Signed-off-by: Masahiro Yamada <yamada.masahiro@...ionext.com>

I will queue this to my kbuild tree.
