buildlink and symlinks to directories

[Mark Davies <mark%ecs.vuw.ac.nz@localhost>]

qt4-tools installs a symlink to a directory

ls -l /usr/pkg/qt4/mkspecs/default
lrwxr-xr-x  1 root  wheel  10 Sep 27 01:17 /usr/pkg/qt4/mkspecs/default -
> netbsd-g++


however when buildlink creates the symlink tree for a package that 
includes qt4-tools/buildlink3.mk this link is not copied resulting in 
potential breakage in packages trying to use it (recent KDE's break).

 ls -l work.i386/.buildlink/qt4/mkspecs/
total 196

      [...]

Any suggestions on how to fix this?
