Failing `wasip1` build after upgrade to cc-1.0.100

[Niederb]

I have a failing build for wasip1 after one of my transitive dependencies upgraded cc to v1.0.100

error occurred: Environment variable WASI_SYSROOT not defined. Download sysroot from github & setup environment variable WASI_SYSROOT targetting the folder.

(See https://github.com/scs/substrate-api-client/actions/runs/9671307108/job/26681692693 for the failing build)
This seems to be caused by this commit: 6a6107a

I'm not quite sure how to fix this. So far we relied on a standard Github runner for our builds and no additional setup for wasi was needed.

cc @antaalt can you help me with this issue please?

I am curious as to how you were building to WASI without a particular setup, for the fix of the build, you can download WASI sysroot from WASI SDK GitHub release pages and setup the WASI_SYSROOT targeting the folder. You will probably still get issues as there is also an issue that need to be fixed with targets

Hello @Niederb can you try cc 1.0.102 to see if it fixed your issue?

Ok I think we'd need to make the WASI_SYSROOT optional, since clang on Linux (or maybe just the Ubuntu-latest runner) seems to come with wasi libraries required.

Just to confirm: cc 1.0.103 fixed the issue for me 👍
