I don't object to the patch.. but we did have multiple problems in the past
where libsdl (native) did not work with the host systems X11 or what-ever.

Various failure conditions about not linking, linking to the wrong libsdl, or
execution failing are what made us prefer the host system's libsdl -- or simply
disabling libsdl altogether.
