On NetBSD, had to add -Wl, -R/usr/local/postgres/lib to the src/Makefile.global LIB variable

Priority: probably low.

Background:
  
  uname -a:
    NetBSD scotts 1.5 NetBSD 1.5 (GENERIC) #1: Sun Nov 19 21:42:11 MET 2000
      fvdl@sushi:/work/trees/netbsd-1-5/sys/arch/i386/compile/GENERIC i386

  Postgresql version: 7.0.3

  To configure I did a `./configure --prefix=/usr/local/postgres'.
  This is straight "out-of-the-box", so I didn't apply any of the
  NetBSD pkgsrc patches.

My problem & fix:

  I had to add -Wl,-R/usr/local/postgres/lib to the
  src/Makefile.global LIB variable.  Otherwise, doing a
  'ldd /usr/local/postgres/bin/psql' after installation
  reported that it couldn't find libpg (`-lpq.2 => Not Found'
  or something like that).

Remarks:

  There's almost certainly a better way, since src/Makefile.global is
  automatically generated, but I'm still getting acclimated to NetBSD
  and Postgres build.
