UnixWare/CVS Tip/initdb.c needs to use threads flags...

I attempted(!) to compile up CVS Head, and if you --enable-thread-safety,
you need to include the THREADS stuff to cc:

gmake[4]: Leaving directory `/home/ler/pg-dev/pgsql/src/port'
cc -O -Kinline initdb.o -L../../../src/interfaces/libpq -lpq
-L../../../src/port -L/usr/local/lib -Wl,-R/usr/local/pgsql/lib -lz
-lreadline -ltermcap -lresolv -lgen -lld -lsocket -lnsl -ldl -lm -lpgport
-o initdb

UX:ld: ERROR: Symbol referencing errors. No output written to initdb

$

Otherwise we don't pick up the threads library where the pthread_* routines
are defined.

(I sent the defines we need in src/template/unixware to Bruce already).
