 I was unable to test gcc 4.8:

 {{{

 -Wl,-headerpad_max_install_names -arch ppc -pipe -Os -arch ppc
 -I/opt/local/include`
 stdout:
 stderr: gcc-mp-4.8: error: unrecognized command line option '-arch'
 gcc-mp-4.8: error: unrecognized command line option '-arch'
 }}}

 GCC 7.. fails with nm issues, so futher work needed to confirm it works
