Bug#945112: debcheck: handle debhelper-compat

[Thorsten Glaser <tg@mirbsd.de>]

Package: qa.debian.org
Severity: normal

 Package declares a build time dependency on debhelper-compat (= 12) which cannot be satisfied on amd64.

Please hack debcheck that it works with these virtual packages. Thanks!
