platform_transition_test appears to break RUNPATH

[molar]

Hello

I am using platform_transition_test on a C++ test binary.
When executing the test remotely it fails because it cannot find the shared libraries in _solib_aarch64 (referenced in the binary using RUNPATH)

The issue appears to be that the "symlink" action does not guarantee to produce a symlink remotely and therefore
our buildbarn worker gets a copy instead, and this breaks RUNPATH resolution (the RUNPATH uses relative locations)

I can work around it in my case by outputting a wrapper bash script that exec's the test binary. Basically changing the symlink action to be this instead

    ctx.actions.write(
        new_executable,
        content = """#!/bin/bash
exec {} 
""".format(original_executable.short_path),
        is_executable = True,
    

However I would like to discuss what could be a permanent solution to this problem
