Stefano reports that after commit 62089b804895 ("kbuild: rpm-pkg:
Generate debuginfo package manually"), building with an rpm package
using rpm 4.20.0 fails with:

  RPM build errors:
      Dependency tokens must begin with alpha-numeric, '_' or '/': #�) = 0x0d000002
      Dependency tokens must begin with alpha-numeric, '_' or '/': �) = 0x0d000000
      Dependency tokens must begin with alpha-numeric, '_' or '/': ) = 0x7c0e000000
      Unknown rich dependency op 'Hat': (Red Hat 15.2.1-7)) = 0x3130363230322000
      Unknown rich dependency op 'Hat': (Red Hat 15.2.1-7)) = 0x4728203a43434800
      Unknown rich dependency op 'Hat': (Red Hat 15.2.1-7)) = 0x3130363230322000
      Unknown rich dependency op 'Hat': (Red Hat 15.2.1-7)) = 0x4728203a43434800

This error comes from the automatic requirements feature of rpm. The
-debuginfo subpackage has no dependencies, so disable this feature with
'AutoReq: 0' for this subpackage, avoiding the error. This matches the
official %_debug_template macro that rpm provides. While automatic
provides should be default enabled, be explicit like %_debug_template
does.

Additionally, while in the area, add the manual debug information
package to the Development/Debug group, further aligning with
%_debug_template.

Please look out for regression or issue reports or other follow up
comments, as they may result in the patch/series getting dropped or
reverted. Patches applied to an "unstable" branch are accepted pending
wider testing in -next and any post-commit review; they will generally
be moved to the main branch in a week if no issues are found.
