When the compiler has "clang" in its name the cc crate will pass
an LLVM target triple to it.  Rust uses a triple that lacks the OS
version and LLVM will default to FreeBSD 9 behavior, i.e., it will
default to libstdc++ which is no longer available in newer releases.

To avoid this issue assume we have a GNU compatible toolchain instead
until LLVM can be updated to use libc++ by default.
