    libtool: Check if -no-canonical-prefixes supported
    
    The compiler fails with the -no-canonical-prefixes flag in certain
    environments. Check if the flag is supported in the current environment
    and skip the test if it is not supported.
    
    * tests/bug_62343.at: Skip test if -no-canonical-prefixes is unsupported
      in the current environment.
