 Thank you!

 At the moment I made a local `ghc-ppc-bootstrap` port, installed `ghc`
 7.0.1 into it and started building `ghc-bootstrap` 7.6.2 with it. If that
 works (it should), then we can add ppc arch to `ghc-bootstrap` right-away,
 provided of course port file will include building procedure for PowerPC
 systems.

 How about adding a new `ghc-ppc-bootstrap` port? I can test it on 10.5.8
 and 10.4.11 prior to submitting a PR.
