Subject: [PATCH] Switch Makefile to compile with g++

With this change I managed to get OpenWrt to compile with uclibcxx
instead of libstdcpp.

Made CXX adjustable by the shell as OpenWrt needs to override this.
It also has its own ar.

EXTRA_CXXFLAGS seems to be the proper variable based on usage in the
OpenWrt tree.
