[PATCH] libsdl-ttf: Update configure.patch

[Richard Purdie <richard.purdie@linuxfoundation.org>]

Update configure.patch to modernise configure.in, in particular passing the
foreign option to automake. The other changes are other modernisations
that were needed to make that.

Also use rm -f so that do_configure can rerun in the prepend.
