So we can't use "automatic -dbgsym packages" as provided by debhelper,
as we have a long standing tradition of trying to avoid needing perl
(and hence debhelper) to build perl.

Seems like the easiest way to implement this manually is to put -dbgsym
packages in debian/control just like regular ones. My reading of the
DAK code (at https://ftp-master.debian.org/git/dak.git/) indicates we
just need to name them perl-dbgsym etc., and declare

 Section: debug
 Auto-Built-Package: debug-symbols.

to get them to go in the debug suite (and bypass NEW processing et al.)

Cc'ing Ansgar, who implemented the DAK side, and Niels, who I understand
designed this whole thing. Is the above correct, or are there other
restrictions? Would we be misusing a private interface between debhelper
and DAK, or are other implementations welcome?

The "Auto-Built-Package" part makes me a bit uncomfortable, it would be
sort of a lie. Is that a problem?
