Well, no, it doesn't do any harm, no. It's just the extra weight of the 
libtool patch in 1/5 plus most lines in this patch.

If the explicit intent is to have debuggable exes for the contrib builds, 
then I guess that's fine. I'd appreciate if that aspect is made clear, 
that the whole libtool patch isn't necessary for anything else than that.
