I thought the issue sounded familiar ...

Meh. It's not clear to me at all that that fixes the issue here,
or at least that it does so in any way that's reliable. The proposal
to add --as-needed during configure was made to fix a different problem,
namely making the wrong decision about whether libintl needs to be
pulled in explicitly. We don't seem to have done anything about that
--- personally I was afraid that it could break as many cases as it
fixed. Reviewing that thread, I still think that swapping the order
of the probes for libintl and libgssapi is the safest fix for the
previous issue.
