RC1, missing -lpthread when building with --disable-shared on i686

L.S.

I noticed the following :

Workstation used to build RC1:

2.4.21-260-athlon, i686 athlon i386 GNU/Linux

Configured with :

./configure
--enable-thread-safety
--disable-shared
--prefix=/usr/src/postgresql/install

Error during make install :

in directory src/bin/pg_ctl

gcc -O2 -Wall -Wmissing-prototypes -Wpointer-arith -Wendif-labels
-fno-strict-aliasing pg_ctl.o -L../../../src/interfaces/libpq -lpq

There seems to be a missing option '-lpthread' here, adding it properly links
the file.

The same goes for pg_restore, pg_dumpall, psql, createdb, createlang,
createuser, dropdb, droplang, dropuser, clusterdb and vacuumdb.
