- Treat g++*, c++* and clang* the same.
- Remove ?= assignments because this isn't a master port.
- Remove libtool dependency.
- Remove pkgconfig dependency. The port only installs a .pc file.
- Disable use of MMX for now. It cannot be used in i386 packages and on
amd64 the compiler already uses SSE.
- Support staging.
- Support WITH_DEBUG.
