[Reproducible-builds] Bug#774496: ncurses: please make ncurses build reproducibly

Hi!

While working on the “reproducible builds” effort [1], we have noticed
that ncurses could not be built reproducibly.

The attached patch will add calls to strip-nondeterminism on static
libraries. Once applied, the package can be built reproducibly with our
current experimental framework.

I've initially tried to run `ar` in deterministic mode by passing
ARFLAGS="Dcrv". Unfortunately, `ranlib` is called after `ar` and there
doesn't seem to be a way to pass the `-D` flag to it, and so it will
write a timestamp in the newly created index.
