The work isn't complete, we have a proof of concept so far. The
remaining work:

* forward port the binutils patch and buildtools-tarball changes to 
  master
* create some mechanism in the autobuilder-helper to download and 
  install (or init if already present) a given buildtools tarball for 
  a given host distro before invoking builds.
* build a set of buildtools tarballs that cover the major gcc verions 
  we need 
* release/publish said tarballs
* add config to the autobuilder for the stable releases we want to 
  build using this mechanism.
* potentially test and debug building older releases

Not sure who is going to do this but it isn't trivial and the work
certainly isn't done yet.

Cheers,

Richard
