To fix this specific issue, it would work to test gettext before
Kerberos. On the other hand, the same thing is going to happen for every
"downward" dependency (where a library higher up in configure depends on
one tested later).

I think I have a pretty good fix: Early in configure, see if the linker
understands --no-copy-dt-needed-entries, or alternatively
--no-add-needed (which is a deprecated name for the same thing). This is
the "light" version of --as-needed: It does not discard unneeded
libraries immediately, but ignores their dependencies. configure
basically works as before, except that indirect dependencies cannot
"hide" required libraries from it anymore.

And a workaround specific to FreeBSD: There is a port for the current
version of binutils (2.22), in which --no-copy-dt-needed-entries is the
default. This can be done relatively easily, by first installing the
binutils port and then installing Postgres with CFLAGS=-B/usr/local/bin .
