cargo wasix suggests incorrect libc replacement

[themighty1]

When compiling a project with a libc dependecy, cargo wasix suggests replacing it with

warn: failed to check dependencies: Found incompatible crates in dependencies (of dependencies): libc

To fix this add the following to 'Cargo.toml':
[patch.crates-io]
libc = { git = "https://github.com/wasix-org/libc", branch = "master" }

But the master branch at https://github.com/wasix-org/libc is an unpatched upstream version (without the wasix patches).
Is this an error? Shouldn't it be suggecting another branch with wasix patches like e.g. [wasix-0.2.155](https://github.com/wasix-org/libc/tree/wasix-0.2.155)
