Sorry for the delay! Had a couple of questions for this one.

This doesn't seem correct. The amd64 binary can run on a powerpc CPU?

Hi @UebelAndre Apologies for the late response, I got assigned to another project.
This one does look like a mistake. But it suggests buildifier was not required at all when I built and tested on my local ppc64le VM. Wondering where it is being used with your Intel builds?

Can you explain this change?

@UebelAndre I had to make this change because one of the required C libraries was not getting found at the expected location. A prefix had to be added to the path but only for the power build and not the Intel build. Please allow me some time to recollect the name of the library and other specifics.

@UebelAndre The library in question is rustix_outline_powerpc64.
The path that was going in with -L was src/backend/linux_raw/arch/outline/release/
It should be external/cui__rustix-0.37.23/src/backend/linux_raw/arch/outline/release , because the library was at the location /root/.cache/bazel/_bazel_root/ff51cf56844f3e41f238392435809bdf/external/cui__rustix-0.37.23/src/backend/linux_raw/arch/outline/release/librustix_outline_powerpc64.a

I hope this makes sense.
