Hmmm.  Is it likely that installing the version from Debian testing
(say) would work ?  Or do we want to build it from source ?  These are
all possibilities.

We could build binutils from source with a job-specific --prefix
setting and that wouldn't stop it sharing the build host with other
jobs.  Maybe it could be a seperate job which provides an anointed
binutils build.

What other awkward requirements are there ?
