commit 85bf9e49f5ab4e0681eeda2549dbd4b5faf3ef7f
Author: Peter Trommler <ptrommler at acm.org>
Date:   Tue May 19 01:21:09 2015 -0500

    Add regression test for #10110.
    
    Module C imports a from Module A and b from module B. B does not
    import anything from A. So if ld is configured to drop DT_NEEDED
    tags for libraries it does not depend on no DT_NEEDED tag for the
    temporary shared object containing module A is recorded in the temp
    SO containing module B. This leads to an undefined symbol when
    linking the temp SO for module C.
    
    Fixes #10110.
