[Buildroot] [PATCH v2] barebox: support multiple image files

Hello,

I've renamed this variable to $(1)_IMAGE_FILES, because it now contains
potentially multiple files.

Applied with this fixed.

BTW, it would be nice to provide a test case for this feature in our
testing infrastructure, see support/testing/. I think in the long run
we should require the addition of test cases when such features are
added.

Thanks,

Thomas
