-E is unfortunately necessary to transfer executable files (which may
be the case for --basefile).

Maybe GNU Parallel should just warn if -E is not working and say that
executables cannot be transferred and then transfer as non-executable
- which would often be sufficient.

I do not have access to a system with old rsync. Can you test what
happens the 4 cases when running rsync -E:

* sender rsync has -E, recipient rsync has -E
* sender rsync does not have -E, recipient rsync has -E
* sender rsync has -E, recipient rsync does not have -E
* sender rsync does not have -E, recipient rsync does not have -E
