Attached is a patch to add __attribute__ ((noinline)) to
call_gmon_start.

Without this patch, the sec script that processed initfini.s removes a
part of inlined call_gmon_start, causing undefined label errors.

This patch solves the problem by forcing gcc not to inline
call_gmon_start with __attribute__ ((noinline)).

Tested by building for arm-none-lixux-gnueabi.  OK to apply?
