   4 # call Makefile for each arch separately, and create fat dylibs at the
   5 # end.  This is because the comm page symbols are added as a special segment,
   6 # which the linker will not thin, so we have to build thin and combine.

  16 # time (for the non-dylib files), and then call lipo to create fat files
  17 # for the three dylibs.
