arch: fix asm-offsets.c building with -Wmissing-prototypes
When -Wmissing-prototypes is enabled, the some asm-offsets.c files fail to build, even when this warning is disabled in the Makefile for normal files: arch/sparc/kernel/asm-offsets.c:22:5: error: no previous prototype for 'sparc32_foo' [-Werror=missing-prototypes] arch/sparc/kernel/asm-offsets.c:48:5: error: no previous prototype for 'foo' [-Werror=missing-prototypes] Address this by making use of the same trick as x86, marking these functions as 'static __used' to avoid the need for a prototype by not drop them in dead-code elimination.
