 Few lines below, same gcc's configure.in does try to test 'hidden' feature
 of binutils older then 2.12.1. As far as I understand, this checking is
 failing. Is'n it?
 
 Generally, I agree that usage of buggy functionality is not a good idea. And
 suppose it is reasonable to ignore it. 
 
 But the implementation does not provide any alternative to 'hidden'. That
 makes __cxa_atexit/__cxa_finalize inapplicable.
