True, with lots of reverse deps it becomes very painful.

We don't support that many external uClibc based toolchains (only arc,
bfin and sh) so I think it's still doable, but ok.

If we can remove the arc 2014.12 toolchain and add the new 2015 one
before 2015.05-rc1 (E.G. end of April) then I'm fine with just disabling
it in the autobuilders for now, otherwise I still think we should add
the depends on !arc-2014-12 to not break it for users.
