Cargo configuration file messes with kernel compilation when using hermit crate #600

Summary

When the crate that depends on hermit contains a Cargo configuration (e.g. .cargo/config.toml), the compilation of the kernel in the build script of the hermit crate will use that configuration.

How to reproduce a failure

Check out this branch which contains a minimal example to reproduce the issue. It contains a Cargo configuration which sets the build target to riscv64gc-unknown-hermit.

Now when you run cargo build, the build fails during hermit's build script. It looks like it's compiling things for the wrong architecture.

This is a known problem, but thanks for opening an issue for tracking this!

This issue exists due to Cargo configuration unification: once a config file in one of the parent directories sets the target, we cannot unset it again. We need to use the host triple for the build script. --target HOST is probably not happening, and unsetting configuration settings is not there yet.

So in your case there is no way around removing the offending cargo config, sadly.
