Build dist-x86_64-musl with --enable-profiler.
Trying to build a Rust project with `-Zprofile` for target
x86_64-unknown-linux-musl using rustc 1.46.0-nightly (346aec9b0
2020-07-11), installed with rustup, results in the following error.
```
export RUSTFLAGS="-Zprofile -Ccodegen-units=1 -Copt-level=0 -Clink-dead-code -Coverflow-checks=off -Zpanic_abort_tests -Cpanic=abort"export CARGO_INCREMENTAL=0$ cargo build --target=x86_64-unknown-linux-muslCompiling hello_world v0.1.0 (…)error[E0463]: can't find crate for `profiler_builtins`
|
= note: the compiler may have been built without the profiler runtime
error: aborting due to previous error
For more information about this error, try `rustc --explain E0463`.error: could not compile `hello_world`.
To learn more, run the command again with --verbose.
```
`-Zprofile` is required here to enable grcov profiling.
This is similar in nature to issue
https://github.com/rust-lang/rust/issues/57257, which has been fixed in
asimilar way at https://github.com/rust-lang/rust/pull/60476 .
A fix for Android has also landed not long ago:

rustcand its tests- The bootstrapping build system
- Various submodules for tools, like rustdoc, rls, etc.
