Title: mosh: fails with llvm

mosh fails to build with llvm-gcc. The original formula forced an ENV.GCC_4_2, which broke under Xcode 4.2. Replace with fails_with_llvm.

It does build correctly with clang. I considered doing something like pixman (which autoselects the right compiler), but that results in a confusing error message to the user when they get the `fails_with_llvm` spiel and then it silently selects a different compiler.
