Bug#797106: libperl5.22: Multi-Arch:same and binNMU changelogs

[Niko Tyni]

Package: libperl5.22
Version: 5.22.0-3
Severity: important

Now that libperl5.22 is Multi-Arch:same, I believe we need to add special
treatment to binNMU changelogs in the same vein as dh_installchangelogs
does (see #708218): break architecture specific binary changelog entries
out into separate files with an arch-qualified path.  Otherwise the
binNMU'd packages will have different contents for an arch-indep
file (/usr/share/doc/libperl5.22/changelog.Debian.gz), preventing
co-installability.

See the thread at https://lists.debian.org/debian-dpkg/2012/07/msg00017.html
for some background. I think the current hack in dh_installchangelogs
is something of a temporary measure but we seem to be stuck with
it for now.

No patch yet...
