Hmm that's strange... The only changes I recently committed are about
NetBSD/aarch64, and nothing about curses/terminfo/termcap have been
changed for a while. mk/terminfo.builtin.mk and mk/termcap.builtin.mk
are only files that can possibly replace -ltinfo with -lterminfo, but
lang/ghc90 includes neither of them.

Does anyone else see the problem happening? I have no idea why this happens.
