Plume version (and/or commit): 3fce5d6a14

After version 3fce5d6a14 Plume fails to build on arm with an error stating rust-lld not found. It looks like wasm isn't building artifacts for arm and a few related tickets are below.

From what I can tell rustup may need some additional components on arm builds that aren't installed by default but I'm not 100% how to progress.

@marek-lach Thank you again 👍

Now to figure out what the necessary linker= pair needs to be on these 2 arm boards (one is arm32 with hardware float, the other arm64)

Current progress. A shell script to build plume-front but it's currently failing with the following error. Shell script included after the error.

I am not sure, @BaptisteGelez might know more about the Rust frontend in Plume, but the lld error you've got looks somewhat similar to this? https://github.com/facebook/osquery/issues/3408#issuecomment-309233430
