Build Hangs on Linux with Nightly Toolchain

Core Problem

The build process for the hypermine repository hangs at the last few steps when using the nightly toolchain on Linux. This issue is reproducible and has been observed both locally on Linux Mint and in GitHub's CI environment.

Solution & Analysis

To reproduce the issue, follow these steps:

Switch to the nightly toolchain:
```
$ rustup default nightly
```

Fetch the hypermine repository:

$ git clone https://github.com/danieldeankon/hypermine.git
$ cd hypermine/
$ git lfs pull

Attempt to build the binaries with verbose output:
```
$ cargo build --release -v
```

The last few lines of the output before the build hangs are:
