Fix oprofile configuration breakage

Browse Source 
The cleanup 09cadedbdc01f1a4bea1f427d4fb4642eaa19da9 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.
