I fear it is more subtle than that, and it is something about
resolving undefined symbols of a static archive (.a) from a dynamic
library (.so) in different GNU ld versions. Notice that it works on my
machine and on the Linux-Fedora15-x86_64_4-gcc-4.6-dbgutil tinderbox.

My machine -> GNU ld 2.22
Fedora15 tinderbox -> gcc 4.6, so presumably a recent GNU ld
Failing tinderboxes: gcc 4.4.5, 4.4.6, 4.3, so presumable older GNU ld

The needed -lkrb5 etc are supposed to be pulled from
$(OUTDIR_FOR_BUILD)/inc/postgresql/libpq-flags.mk,
which exports the *exact* -lfoo arguments that upstream postgresql
would have used to create libpq.so, so it seems improbable to me
-lkrb5 is missing. If a failing tinderbox operator could check that,
and/or see the postgresql-build with verbose=T, so that we can exclude
that for certain?
