I'm not sure there is anything which can usefully be fixed in libva:
* The shared libraries themselves have the right internal linking (DT_NEEDED),
so they don't need anything extra at link time.
* Static linking libva isn't really supported at all - libva depends on dynamic
linking, including being able to find its own symbols backwards from a
dynamically-loaded driver binary. (It's probably possible by some method
involving --export-dynamic, though I haven't tried.)
Anyway, applied. I'll backport to 4.1 as well, since that was where the
original report came from.
Thanks,
