    Fix "elf: Add tst-ldconfig-ld_so_conf-update test" on 32bit.
    
    This new test was introduced with recent commit
    591236f1a33f11cc65ccf009d997071ba853e186.
    If run on 32bit, it fails while renaming tst-ldconfig-ld-mod.so as there is no
    /usr/lib64 directory. This patch is constructing the file name with help of
    support_libdir_prefix.
