Zig fails to build: SIGILL

I’m running `zig build-exe hello.zig` which returns ` fish: Job 1, 'zig build-exe hello.zig' terminated by signal SIGILL (Illegal instruction)`.

hello.zig is
```zig

const std = @import("std");

pub fn main() !void {
const stdout = std.io.getStdOut().writer();
try stdout.print("Hello, {s}!\n", .{"world"});
}
```

dmseg is:
```
