First thing you can probably try is instead of setting --install-prefix=/usr, you can do -DCMAKE_INSTALL_PREFIX=/usr. If that doesn't work then you might want to look at your dynamic linker and see if that's working right. These warnings look suspicious:

You nees to set correct dynamic linker using -DZIG_TARGET_DYNAMIC_LINKER=<path> option.

Do you have multicall USE flag set on sys-apps/coreutils? If so, your /usr/bin/env is a script and Zig incorrectly recognizes it as full executable, which leads to your error:

https://github.com/ziglang/zig/blob/3c5e840732053318f5e722d6cc16f65d51cdc297/lib/std/zig/system.zig#L999

buffer.len is 255

https://github.com/ziglang/zig/blob/3c5e840732053318f5e722d6cc16f65d51cdc297/lib/std/zig/system.zig#L1032-L1035

Tries to read at least this amount of bytes from file, fails and breaks file as ELF file/(finishes too early).

https://github.com/ziglang/zig/blob/3c5e840732053318f5e722d6cc16f65d51cdc297/lib/std/zig/system.zig#L1068-L1073

Tries to parse this as ELF file, but it's too short, here error logs.

Yes the USE flag multicall is set on sys-apps/coreutils triggering the bug. Thank you for solving the problem.

USE flag multicall is set on sys-apps/coreutils triggering the bug.

Doesn't multicall just make it /usr/bin/env into a symlink to the real ELF? And we should support that out of the box.
