gbp issues when building for Deb9+

[aderbenev]

Adding some to my big pile of packaging debt. When this is built for Deb9 or Deb10, there are two issues:

1. pod2man --release= cannot be blank, it results in error. Passing empty "" string there fixes the issue.
2. Debug symbols are being generated, which results in reprepro being unhappy.

Fix:
