Can you demonstrate any user-visible effect of this? I thought it implied
that lookup could go awry if there were an object with only DT_HASH and no
DT_GNU_HASH with a SHN_UNDEF symbol of a given name that's earlier in the
search order than the object that actually defines that name. But I tried
a simple test case and that does not seem to be so.
