    testsuite: Add profile_update_atomic check to gcov-20.c [PR114614]
    
    As PR114614 shows, the newly added test case gcov-20.c by
    commit r14-9789-g08a52331803f66 failed on targets which do
    not support atomic profile update, there would be a message
    like:
    
      warning: target does not support atomic profile update,
               single mode is selected
    
    Since the test case adopts -fprofile-update=atomic, it
    requires effective target check profile_update_atomic, this
    patch is to add the check accordingly.
