[ Upstream commit aacf93e87f0d808ef46e621aa56caea336b4433c ]
Another oddity in these config entries is their default value can fall back to 'n', which is a value for bool or tristate symbols.
The '|| echo n' is an incorrect workaround to avoid the syntax error. This is not a big deal, as the entry is hidden by 'depends on RUST' in situations where '$(RUSTC) --version' or '$(BINDGEN) --version' fails. Anyway, it looks odd.
The default of a string type symbol should be a double-quoted string literal. Turn it into an empty string when the version command fails.
