It's not needlessly since it fixes builds when libx264 is built against
external libs to the least, without a hack of trying to guess what library
could be needed. It simplifies the creation of static builds. And also it
simplifies specifying a custom x264 build. Finally, it's the official
supported way of linking to x264.

It indeed might break some scripts that used to workaround the previous
issues with --extra-{c,ld}flags. But that's the reason we are documenting
the change, and also displays a very obvious error in case it fails.
