toolchain/gcc: clean up CFLAGS 

Instead of having two different ways to pass flags to the gcc build
process, add them as configure args, which is a reliable way to let
gcc pass them around to its various pieces.

Also add CXXFLAGS, since gcc started to use c++ for itself recently
(~10 years ago now).
