how about this logic:

if cpu is ppc
  if as exists
    if as is apple version
      use as
    else if as is gnu version
      use as to assemble but src/libFLAC/ppc/gas directory
    else
      no asm
  else if gas exists
    use gas
  else
    no asm

?

could you also send me version strings for your versions of
as/gas for whatever combination of PPC,OS that you have?
