We don't want C specific flags in GST_CXXFLAGS, so base it on the
GST_CFLAGS that only contains the pkg-config CFLAGS but none of
the GST_OPTION_CFLAGS. Also, we only need the local includes once.
dnl prefer internal headers to already installed ones
dnl also add builddir include for enumtypes and marshal
dnl add GST_OPTION_CFLAGS, but overridable
