    testsuite: enable use of cxa_atexit on module pr98893 test
    
    Targets that don't have -fuse-cxa-atexit enabled by default don't get
    the expected __tcf_ZL1b symbol.  Require and enable the use of
    cxa_atexit.
    
    
    for  gcc/testsuite/ChangeLog
    
            * g++.dg/modules/pr98893_b.C: Require and enable cxa_atexit.
