    Fix elf/tst-tls9-static after libdl cleanups.
    
    The testcase elf/tst-tls9-static sometimes fails with:
    cannot open 'tst-tlsmod5.so': tst-tlsmod5.so: cannot open shared object file: No such file or directory
    cannot open 'tst-tlsmod6.so': tst-tlsmod6.so: cannot open shared object file: No such file or directory
    
    After recent commit
    6f1c701026287f6928d3bdd1aea7359308635abe
    "dlfcn: Cleanups after -ldl is no longer required"
    the libdl variable is not set anymore and thus the
    dependencies were missing.
