[bug#70985,v3,5/6] gnu: rust: Guard against unsupported rust targets.
 
Commit Message
  
  
As cross-libc may return #f in this case, and the config.toml file
construction will also fail if the platform rust-target is #f..
* gnu/packages/rust.scm (make-rust-sysroot/implementation): Guard against
unsupported rust targets.

I like this. We can always add more platforms later with their
platform-rust-target later as needed.
