    rtld: allocate obj->vertab only once
    
    Verbatim from FreeBSD SVN 233546 (27 MAR 2012)
    
    Prevent rtld_verify_object_versions() from being called several times for
    the same object. This can happen when object is a dependency of the
    dlopen()ed dso. When called several times, we waste time due to unneeded
    processing, and memory, because obj->vertab is allocated anew on each
    iteration.
