Log:
  powerpc/dtrace: Fix fbt function probing for ELFv2
  
  '.' function names exist only in ELFv1.  ELFv2 does away with function
  descriptors, and look more like they do on powerpc(32) and most other
  platforms, as direct function pointers.  Stop blacklisting regular function
  names in ELFv2.
