When BR2_PACKAGE_XSERVER_XORG_SERVER is enabled, the .mk file also
depends on xlib_libX11, so I believe you should add a:

	select BR2_PACKAGE_XLIB_LIBX11 if BR2_PACKAGE_XSERVER_XORG_SERVER

here.

Also, you need to propagate the BR2_LARGEFILE dependency of
BR2_PACKAGE_LIBDRM.

You can add:

LIBVA_LICENSE_FILES = COPYING

Are you sure that GLX support is always available as soon as mesa3d is
enabled? I believe that GLX is the protocol used to do OpenGL under
X.org, but Mesa3d is usable outside of X.org.

This would need a:

LIBVA_DEPENDENCIES += libegl

otherwise, the egl implementation is not guaranteed to be available
before libva gets built.
