We already have configure.compiler settings for llvm-gcc-4.2 and clang.
Port maintainers can use these as desired. We default to whatever Apple
calls /usr/bin/cc on each OS.
There's a default for darwin 11 in base already on spec (llvm-gcc-4.2).
We can change that if it turns out to be wrong when Lion ships.
Otherwise this should all "just work".
