[patch] Fix readelf to print versions for non-default symbol versions

I'm withdrawing this patch, at least until I understand things better.

I think the VERSYM_HIDDEN bit should not be set for references to the
VERNEED section, which is what this section of code is dealing with.
It turns out that gold is (I think) erroneously marking an undef in
the VERSYM section with the HIDDEN bit.
