commit r12-7707-gc5086228cd79f7baa7d8d3c4bba04a69ab756253

    testsuite, modules, Darwin: Adjust expected output for older OS versions.
    
    Darwin versions <= 10 (macOS 10.6) emit different diagnostics for the failure
    case being tested by bad-mapper-1.C.  Adjust the dg- expressions to reflect this.

    gcc/testsuite/ChangeLog:
    
            * g++.dg/modules/bad-mapper-1.C: Make dg- expressions that match the
            diagnostics output by earlier Darwin too.
