    Change GL_INLINE to also include the always_inline attribute for GCC
    
    This ensures that gcc always inlines the funciton in question, regardless
    of current optimization level. Otherwise android cross-builder fails
    to link glib due to undefined references to xsum and other pure
    inline functions.
