This has been reported by a Debian user.

make is currently linked against librt and therefore libpthread,
despite using no routines in either library.  This wastes memory.  The
problem is an oversight in the configure script, which causes librt to
be linked even when the functions from it aren't going to be used.

Please apply the appended patch.
