Debian has been carrying the included patch for a while, originally added against 2.1.22 with:

+ Fixed the undefined symbols in libldap_r.so.2 (closes: #195990). | configure.in: Try -lpthread before -pthread to link the thread library. libtool does not pass -pthread through, -lpthread seems to work though.

and then refreshed some time later against 2.2.23 with:

* configure.in: reinstate the remainder of the fix for 195990 from 2.1.22-2: give preference to -lpthread over -pthread in configure.in, because some archs (mipsel, at least) don't like -pthread.

A quick search of other ITSes didn't reveal this particular report, but it did look like people building on AIX were manually setting library flags that may produce the same result. I'm sure that none of Debian's platforms will break with -lpthread instead of -pthread since we've been using this for a while, although I'm not sure if that's sufficient.

I'd ideally like to see Debian stop carrying this patch around as a divergence, particularly since it means that the package has to re-run Autoconf during the build.
