Fix broken symbolic links in release tarballs.

Fix broken symbolic links in release tarballs.

Now, when the release is created (make distfile) the symbolic links
are followed.

Another solution could be to create relative links in "make build*".
However, I preferred to dereference the links for two reasons:
- it is simple;
- it allows uncompresing our release also in filesystems not supporting
  symlinks.

Land as is.

Very nice.  Didn't know about that option.  Thank you.
