Why? This seems unrelated to the change.

Why are you adding this option, while all other options are enabled
automatically?

What about just:

	select BR2_PACKAGE_FFMPEG_AVRESAMPLE if BR2_PACKAGE_FFMPEG
	select BR2_PACKAGE_FFMPEG_SWSCALE if BR2_PACKAGE_FFMPEG

And then, in the .mk file:

ifeq ($(BR2_TOOLCHAIN_GCC_AT_LEAST_4_8)$(BR2_PACKAGE_FFMPEG),yy)
...
endif

I didn't notice until now, but we'll have issue with comma separation
when appending things this way. You should have a look at
package/qt/qt.mk to see how it was solved.

This is really horrible. Could you instead fix the libvpx integration
to make it work? Report the problem upstream so that it get fixed? Use
the external version of libvpx?

Thanks!
