For some context:  NetBSD's config for libtool was taken from SunOS's way
back in NetBSD 1.3 (because SunOS was also a.out); we didn't know at the
time that the config for SunOS was wrong.  soda emlightened me yesterday
about it.

HOWEVER, NetBSD is not the only affected platform.  Note that libtool does
the same for:

- NetBSD a.out (which may need .major.minor, rather than .major.minor.teeny)


- FreeBSD a.out (same note as NetBSD a.out, but may not be supported by
  pkgsrc anyway at the moment)

- Darwin (*after* the change in pkgsrc's patch-ac for libtool; without the
  patch, it does the "correct" thing)

- Solaris ("SunOS 5")

- OSF/1 (pkgsrc is not supported on this at the moment)

I can fix libtool for NetBSD plus the supported platforms above, but this
will require the following (not all of which I necessarily have the time to
do right now).  "Flag days" are very bad, so this should be done in a way
that keeps pkgsrc atomically correct.

A single commit to pkgsrc should do all of the following:

1. Change libtool, bump its PKGREVISION.

2. Bump _OPSYS_LIBTOOL_REQD to the new version in

3. Bump the PKGREVISION of all USE_LIBTOOL packages, and all their direct
   dependencies (but not indirect dependencies); this will unfortunately
   impact all platforms, but it's unavoidable.

4. Bump the of any packages bumped in (3) above,
   so that default builds will require the new shlib major/minor values,
   but experienced pkgsrc users may override this to allow for phased
   upgrades (leaving some old pkgs installed temporarily if needed).

As to the changes noted in the PR:

The above is the correct change.
