[Mesa-dev] [PATCH] fix vdpau interop when using -Bsymbolic-functions in ldflags

[Maarten Lankhorst]

Explicitly add radeon_drm_winsys_create and nouveau_drm_screen_create to
the dynamic list. This will ensure vdpau interop still works even when
the user links with -Bsymbolic-functions in hardened builds.
