[Rpm-maint] [rpm-software-management/rpm] Make macro %{error:...} cause an actual failure (94e8cd6)

[Jeff Johnson]

Causing a full stop failure during expansion raises expectations to provide better RPM error messages, or behave more gracefully.

The expectations often cannot be met because macro expansion is context free (by design).

Debugging a macro expansion that is exiting is often harder than printing whatever and continuing a package build. There are simply too many ways for templated macro expansions to go off the rails for %error to be really useful.
