One thing I've been wondering about would be to remove the 'check phase
when building a rust that will be used for bootstrapping only. Since the
tests are not ran in parallel, they take a huge amount of time.

See attached patched, I'm testing it now. It's currently building
rust <at> 1.23. WDYT?

Thanks,
Pierre
