[libdv-dev] Patch to configure.in allowing --disable-sdl

[Scott F. J. <sc...@fl...>]

This is a quick patch to configure.in to allow the use of --disable-sdl
when running configure. This results in a gtk-only version of playdv and
makes it easier for testing various configurations.
It also prevents configure from checking to see if SDL is installed,
allowing
libdv to build on machines without SDL, or with SDL < 1.1.6.
After applying, run autoconf to build a new configure script from
configure.in.
