    library-template: Use AX_CHECK_ENABLE_DEBUG for debug compiler flags
    
    This removes another load of boilerplate.
    
    http://www.gnu.org/software/autoconf-archive/ax_check_enable_debug.html
    
    We use the AX_IS_RELEASE macro to check whether to enable debug by
    default, using the micro-version policy.
