Doesn't look like you're using symlink(), so you can remove this.

Done.

Bonus points if you made this work for target_os="android".

To do so, wrap the target in:

if (current_toolchain == host_toolchain) {}

And in the root BUILD.gn, do:
deps += ["//tools/origin_trials/validate_subdomain_origin($host_toolchain)"]

I made the change, but I'm wondering if it applies here? This utility is meant
to be used from the command line or called from the generate_token.py script. I
don't see that happening on Android.
