Building GHC head with clang on Mavericks

[Kazu Yamamoto (=?iso-2022-jp?B?GyRCOzNLXE9CSScbKEI=?=)]

Hi,

I can finally build GHC head on Mavericks. I gave up on clang and
installed GHC 4.8 with MacPorts.

Then, I compiled alex and happy with GHC 7.6.3/GHC 4.8. With this, I
can build GHC head.

This step is a MUST. If alex and happy are complied GHC
7.6.3/clang-wrapper, I cannot build GHC head with GHC 7.6.3/GHC 4.8.
