Description of problem:

  systemd-devel obsoletes the arched libudev-devel-package, but
  does just carry an unarched Provides for it.


Version-Release number of selected component (if applicable):

  any, since obsoletion


How reproducible:

  100%


Steps to Reproduce:
1.  Have another -devel-pacakge Requires: libudev-devel%{?_isa} as
    required by packaging-guidelines.
2.  *BOOM*


Actual results:

  Dependencies cannot be resolved, though systemd-devel obsoleted
  libudev, but does not provide all provides of libudev.


Expected results:

  All provides of libudev-devel are properly present in systemd-devel,
  so depending -devel-packages can have requires as obligated by
  packaging-guidelines.
