ax_compiler_flags: Adapt for AX_COMPILER_FLAGS_CXXFLAGS
Use the new AX_COMPILER_FLAGS_CXXFLAGS macro in AX_COMPILER_FLAGS to
test for available C++ compiler warning options, and AC_SUBST them as
WARN_CXXFLAGS. Pass the EXTRA-*-CFLAGS variables to
AX_COMPILER_FLAGS_CXXFLAGS, to avoid an explosion of arguments, and as
most C++ warnings are also valid C warnings.
