  Here's where it fails...

  tmp-popcount.s:122:vspltisb vector instruction is optional for the 
  PowerPC (not allowed without -force_cpusubtype_ALL option)
  tmp-popcount.s:123:vspltisb vector instruction is optional for the 
  PowerPC (not allowed without -force_cpusubtype_ALL option)

That is a confusing error message.  Clearly, we pass the strangely
named -force_cpusubtype_ALL option.  What does the error message suggest?
That we pass it again?

I cannot address this, as I don't understand what to do about it.
Somebody with a Mac OS X 10.3.9 needs to work on it.
