Hi Masahiro,

It is the `RUSTC_BOOTSTRAP` environment variable: it allows to use
unstable featuers in the stable compiler.
We currently set it in the global `Makefile`, but we could be more
explicit and do it on each command if you think that would be better.
If you want that we keep using the global export, then we can add a
comment explaining this to clarify.
Cheers,
Miguel
