new cabal install binaries

[Gershom B]

when we build the new platform we're going to have new cabal-install
binaries for 2.0.1.0. It would be better if we provided the same ones
as provided on the cabal website. Is there anyone lined up to build
any of these, or would you like the platform team to provide you with
the binaries we build as well? (i know i've done mac in the past, and
will happily do so again, but typically there have been other sources
for linux and windows binaries).

Cheers,
Gershom
