after new release 0.1.20 the build seems broken. The docs doesn't the reflect the changes.

Hi,

after new commits I'm not able anymore to build a project with hermit-sys as dependency, it seems related to a change in the build toolchain and config.

Here the log:

error: failed to run custom build command for hermit-sys v0.1.20

Yes, I notice this issue. The latest version should fix. Does it work on your systems?

[alessio-proietti]

The fact is I have to use the exact toolchain nightly indicated in a file here in the repo and not the latest... so it builds now but I sort of reverse engineered the build

[stlankes]

Every day to switch the toolchain is difficult. Do you get with the current night some errors like "unknown token in expression"?

[stlankes]

hermit-os/kernel#192 should fix this issue.

[alessio-proietti]

I'll try with newer version.
