Currently rustrt is built with -O0 on the Mac due to a GCC bug. This is starting to cause performance problems; in particular, very suboptimal assembler is generated for next_power_of_two, which is the third-highest function in the profiles. Apple's GCC is way outdated anyhow.

Will anyone object if I make clang a dependency on that platform?
