  PowerPC: Detect AltiVec support on OS X
  
  libjpeg-turbo's AltiVec SIMD extensions previously assumed that AltiVec
  instructions were available on all Power Macs that supported OS X 10.4
  "Tiger" (the earliest version of OS X that libjpeg-turbo has ever
  supported), but Tiger can actually run on PowerPC G3 processors, which
  lack AltiVec instructions.  This commit enables run-time detection of
  AltiVec instructions on OS X/PowerPC systems if AltiVec instructions are
  not force-enabled at compile time (using -maltivec).  This allows the
  same build of libjpeg-turbo to support G3, G4, and G5 Power Macs.
  
  Closes #609
