Steps to Reproduce and Observed Behavior

I build zig from source with llvm and clang 21 also built from source. That went well.

Cloning zls repo and building with zig results in following error:

error: the following build command failed with exit code 1:
.zig-cache/o/39970f6c93516ccfff6593f2d3e0db46/build /home/lukeflo/Documents/packages/zig/build/stage3/bin/zig /home/lukeflo/Documents/packages/zig/build/stage3/lib/zig /home/lukeflo/Documents/packages/zls .zig-cache /home/lukeflo/.config/cache/zig --seed 0x171d9ac5 -Zbead826ac2a2a6e2 -Doptimize=ReleaseSafe

Expected Behavior

That the zls master branch build without errors against the current zig master branch.

Log Output

None, since `zls` isn't built successfully.
