I think it's fixed now.  Have a look at the patch and perhaps try it
out on a non-haiku system and see if it correctly detects needing -lm
on that system.  If it does let me know, this might be worth sending
back upstream.
It's nice to have joe working on haiku, now i won't have to fight with
vim to do a check in ;)
