After a bunch of experimenting and testing it turns out that the remote build commands complain about not being able to find the identity file if it's quoted within the remote-systems.conf file.
Even when using single quotes it complains.
Given that home dirs for the target platforms can't (or are incredibly unlikely to) have spaces in their path, can't see that it is an issue to remove the quotes.
Resolves #20
