I think I'll just move the --target-os option back into the cross
compilation block which will at least fix the native build. In the above
commit it was only the --arch option which was important to always specify.

Maybe upstream FFmpeg could be taught to accept "hurd" as an alternate
name for "gnu" in --target-os?
