    testsuite, Darwin: Fix darwin-comm-1.c error messages for Darwin <= 10.
    
    When amending the allowed alignment size to accommodate the larger values
    permitted by newer tools, we retained the object file limit of 2^15 for
    Darwin versions <= 10, since that is what the native tools expect there.
    
    This triggers a different diagnostic path with a distinct error message,
    which is checked in the revised test here.
