1. I think --with-gcc= is independent of the llvm code generator.
2. Building the llvm codegen does not necessarily make it the *default*
codegen; I think native remains default.  I don't know if there's a way to
specify that llvm should be the default code generator.

fwiw, the ghc I have on here does not mention llvm in ghc --info, but ghc
-fllvm at least tries to work.
