Hi Joerg,

I think I mentioned more things than inverting branches:

  + I think we should be using Triple::getSubArch rather than string matching.
  + It needs to be plumbed into gnutools::Link; I'd prefer the other
BSDs too (at least if they show hints of ARM & BE support), but that's
not fatal because we may be incorrect about the desired behaviour and
to my knowledge they haven't said anything.

I may have mentioned other things, but can't see them now if so (part
of why I dislike code review on IRC: there's no record). I'll check
when I get home.

Cheers.

Tim.
