    testsuite, c++, Darwin: Add crt to LTO link line for darwin9.
    
    The LTO tests here are hand-crafting link lines, to build a shared
    library on Darwin8/9 we have to provide a crt that contains the
    header.
    
    gcc/testsuite/ChangeLog:
    
            * g++.dg/lto/pr86585_0.C: Add -dylib0.o for Darwin8/9.
            * g++.dg/lto/pr87906_0.C: Likewise.
