Right, but if you remove the $DESTDIR/$libdir from the relink command,
then you'd break these native builds (because, e.g. /usr/lib is still in
the compiler's default search path).

For instance, suppose you're building gettext: it installs several so's
(with interesting dependencies between them) AND a bunch of executables
that depend on THOSE so's.  If you use $DESTDIR, and need to relink, but
don't include $DESTDIR/$libdir in the -L spec, then you'd relink the
executables (and so's with internal dependencies) against the versions
installed by gettext-$OLDVER in /usr/lib.

If the new apps depend on any added/new interfaces...boom.
