I think the right thing to do is to add --with-* flags for
(n)curses/termcap; the alternative would be to put the whole of $LDFLAGS
into the Cabal buildinfo, but that feels wrong to me.

We should probably also be undefining variables like LDFLAGS in
configure, as the autoconf macros will be using them to check if
libraries exist, but we don't use them when compiling.
