Title: gambit-scheme: warn that building with clang or LLVM-GCC takes awhile.

The Gambit Scheme configure script warns that building Gambit Scheme with clang or LLVM-GCC takes a really long time, and it's right. The first couple of times I tried building it after installing Xcode 4.2 (or whichever version dropped gcc-4.2), I was convinced that the build had hung.

Since the Homebrew user won't see the configure script warning, this patch lets the user know that an inordinately long build time is the expected behavior when using clang or LLVM-GCC.
