Whatever it was now the runtime is broken instead. USE_GCC is unsafe to
use with C++ projects that have dependencies linked against libc++.

  $ pkg install musicpd

  $ musicpd
  terminate called after throwing an instance of 'std::runtime_error'
  Abort trap

  $ ldd /usr/local/bin/musicpd | fgrep c++
          libstdc++.so.6 => /usr/local/lib/gcc5/libstdc++.so.6 (0x29e85000)
          libc++.so.1 => /usr/lib/libc++.so.1 (0x2a42d000)
