Applied to master after fixing a few typoes, and adjusting the commit
log/comments with the fact that it was indeed working for me because I
had libtool installed. So the problem is not just the fact that the
symlinks are not overwritten by autoreconf, but that they are not
overwritten if they are broken symbolic links in the first place.

Thanks!
