update from 6 to 7 - needs libtool rebuild

I updated from 6-stable to 7-stable and got the following error
when portupgrading graphics/tiff...

/bin/sh /usr/local/bin/libtool --tag=CXX --mode=link c++   -O2 -fno-strict-aliasing -pipe  -L/usr/local/lib -o libtiffxx.la -rpath /usr/local/lib -no-undefined -version-number  4:0:0  tif_stream.lo ../libtiff/libtiff.la ../port/libport.la -ljpeg -lz -lm -lc

/usr/bin/ld: cannot find -lgcc_pic

As it turns out, a forced update of libtool was needed.

There are a few key differences between old libtool-1.15.26 from
6.x and the rebuilt one in 7.x

Below is just an excerpt of the diff.  Note the references to
i386-portbld-freebsd6.3 (in the old) and i386-portbld-freebsd7.1 (in
the new).  And the key for the issue reported above: lgcc_pic replaced
by lgcc_s.

[I'm not sure why the new lib search path has "/usr/lib /usr/lib"
 and later "-L/usr/lib -L/usr/lib", but that duplication is minor]

[ see also http://www.freebsd.org/cgi/query-pr.cgi?pr=113172 ]

So my question is: is this documented and/or widely known?  A full
portupgrade wouldn't help if you were up to date on libtool in 6.x
before updating (unless portupgrade -f is used).

If this isn't widely known, maybe this will help someone.

Would it be worth documenting this in UPDATING (if I haven't
missed it somewhere)?

I wonder if there's a good way to have this staleness on
OS update detected by our port/pkg update tools.
