I guess that's because of this change:

  99649: Eli Zaretskii 2010-03-12 Don't use termcap.c on Posix platforms

I'm sorry for the breakage this caused.  In my defense I can only say
that it "worked for me" on GNU/Linux.  At the time this issue was
discussed, I published the list of changes needed to stop using
termcap.c on Posix platforms, based on what's been said during the
discussion, see

  http://lists.gnu.org/archive/html/emacs-devel/2009-12/msg00276.html

No one said anything else should be done.

Feel free to add the missing pieces to the configury to fix this.
