[Buildroot] EXTRA_DOWNLOADS broken when SITE_METHOD = git

Luca, All,

Thanks for this report. I can indeed confirm that extra downloads are
broken on 2018.02.x and master, when the main download is from an SCM.

As I said on IRC, I think they have always been broken, but we silenly
failed so far. So, there is no "regresskion" per-se. Just a bug.

As for master, we no longer silently fail, but we do now error out.
This could be considered an improvement, no? ;-)

I am working on a fix, and I already have something that is workable
now. I jsut need a few tests, and I'll submit it later tonight (or by
the weeke-end at least).

Regards,
Yann E. MORIN.
