Status update:

- I've got a rustc bootstrap build (using upstream binaries) ready for
buster/stretch, using LLVM 7 and no wasi-libc.
- cargo using the above rustc and buster/stretch's cargo (no bootstrap necessary)
- cbindgen building with the above

That avoids the LLVM 9/10 update for this round.

I'm currently attempting a build of Firefox 78.2.0 ESR for buster. If that goes
well I'll start uploading things to buster (coordinating with the SRMs).

Cheers,
Emilio
