Some packages don't support cross building to specific targets, so add a error
type to signal this.

* guix/packages.scm (&package-unsupported-target-error): New condition type.
[package-unsupported-target-error? package-unsupported-target-error-target):
New procedures.
* guix/ui.scm (call-with-error-handling): Handle this new condition type.
