kbuild: merge generic-asm-offsets.h and asm-offsets.h rules
The rules "cmd_generic-offsets" and "cmd_offsets" are almost the same. (The difference is only the include guards.) They can be merged. This commit is mostly inspired by the following commit of Linux. commit 39664e2f3cdef98f42437e903159a6044a1d99d6 Author: Masahiro Yamada <yamada.m@jp.panasonic.com> Date: Mon Jan 5 15:57:15 2015 +0900 kbuild: merge bounds.h and asm-offsets.h rules Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
