Fix oprofile configuration breakage

The cleanup 09caded broke the oprofile configuration for MIPS by allowing oprofile support to be built for kernel models where oprofile doesn't have a chance in hell to work. Just a dependecy list on a number of architectures is - surprise - broken and should as per past discussions probably in most considered to be broken in most cases. So I introduce a dependency for the oprofile configuration on ARCH_SUPPORTS_OPROFILE. Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
