[PATCH] Fix testsuite regression caused by r271077

[Jonathan Wakely]

        * g++.dg/cpp0x/Wattributes1.C: Adjust dg-error line number to fix
        regression, by matching a note on any line.
        * g++.dg/cpp0x/Wattributes2.C: Add another copy that checks the
        correct line number is matched without depending on a library header.

Tested powerpc64le-linux, OK for trunk?
