Details
We use a forked lucet compiler to compile wasm modules. Lucet only recently added support for cross compiling wasm files. Since Firefox on Mac is cross compiled in the try servers, we need to backport the patch supporting cross compilation to our fork (or rebase our fork).

Backport is complete and is located in https://github.com/PLSysSec/lucet_sandbox_compiler, rev=07405987fcbc7390c08b49bc590034956861a522
@Nathan: Could you direct me to where I can change the prebuilt lucet downloaded as part of mach configure?

Once you change what sources lucet is built from, mach bootstrap (from a tree with the necessary changes) will just download the binary built with the updated sources. There's nothing to change in mach configure because configure doesn't download software. Does that answer your question?

Sorry, slight mistake on my part. I meant "where can I change the what sources lucet is built from so that bootstrap will be updated appropriately"

Ah, sorry! You need to change the git revision here:
https://searchfox.org/mozilla-central/source/taskcluster/ci/fetch/toolchains.yml#446-451
Changing that will update both builds on automation and the binary downloaded by bootstrap.
