This patch is similar to Tomoki Sekiyama's [PATCH v9 01/10] configure: Support configuring C++ compile, with the main differences being: not using "c++" as default compiler, instead do not enable by default (requires explicit CXX env, --cxx option or cross-compilation prefix) separate CFLAGS and CXXFLAGS in the default way.
