    build: adapt for AX_CODE_COVERAGE API break
    
    The usage of AX_CODE_COVERAGE has changed since autoconf-archive version
    2019.01.06.
    
    Unfortunately it is not sufficient. It triggers a bug in
    AX_CODE_COVERAGE that is fixed in autoconf-archive git master but not in
    the latest stable version (2019.01.06).
