running clang compiler test suite from within macports infrastructure?

[Ken Cunningham]

This test suite proved very very helpful!

Clang-3.8 on PPC produced only 13 errors out of 500 tests. 

10 of those were on the same issue, 32bit exceptions.

The other three included on a weird math error in fast-fourier-transfroms, and two errors in the logic of handling certain va_args (which I thought we had fixed).

Gives me encouragement to continue on with clang-3.8 on PPC.
