Kinda sorta did:

+# This patch removes the hard dependency on backtrace by checking for
+# it at compile time and adds a cross-compile /proc check.
+# Patch given to me by Hisham <hisham.hm at gmail.com> (htop-general)

Hisham is the main developer.  You want me to modify this patch 
again and resubmit?  I don't mind -- and it wouldn't take long.
