Issues with `aarch64-unknown-linux-musl`

[JonathanWoollett-Light]

Problem

When attempting to build with the --target=aarch64-unknown-linux-musl target it produces the error:

   Compiling test-lib v0.1.0 (/home/ec2-user/test-lib)
error[E0463]: can't find crate for `profiler_builtins`
  |
  = note: the compiler may have been built without the profiler runtime

For more information about this error, try `rustc --explain E0463`.
error: could not compile `test-lib` due to previous error

Steps

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y
source "$HOME/.cargo/env"
cargo new test-lib
cd test-lib
rustup target add aarch64-unknown-linux-musl
export RUSTFLAGS="-Cinstrument-coverage"
cargo build --target=aarch64-unknown-linux-musl

Possible Solution(s)

It has been suggested this may be a specific issue with the -Cinstructment-coverage flag not currently being supported in this toolchain.

Notes

I've been suggested a related PR: rust-lang/rust#79556.

I found a similar issue rust-lang/rust#81684.

This is most likely related to rust-lang/rust#79556.

[briansmith]

Is this fixed after rust-lang/rust#111575 added the profiler builtins for this target?
