Correct me if I'm wrong, but I don't think implementing auto linking
support in GCC is a realistic goal. I can imagine there are lots of
technical and non-technical issues involved, it's certainly not
something that can be accomplished in the short term.

Yeah, take a look at the comments in the report Roger linked to. It
looks like we can't handle multiple variants with pkg-config. I don't
think this is a major problem for the time being, though, as there's a
single variant in Debian and I imagine that's also the case for most
other distributions.
I think proper pkg-config support would be fantastic. I'm wondering if
this support could be patched downstream in case upstream rejects or
ignores the patches Roger submitted. I'll adapt btag's build system to
use pkg-config for Boost as soon as this enters unstable.
