[Debian-on-mobile-maintainers] Bug#996699: chatty: Cross-building fails to resolve libpurple-dev

[Travis Wrightsman]

Package: chatty
Version: 0.4.0-1
Severity: serious
Justification: fails to build from source
Tags: ftbfs upstream

Chatty fails to cross-build due to a dependency resolution error for the
libpurple-dev package.

I'm not sure this is a chatty-specific bug but I'm also not sure where
else to place it.

It occurs on Debian Salsa builds:
https://salsa.debian.org/DebianOnMobile-team/chatty/-/jobs/1940649#L1475

It also occurs when using git-buildpackage to cross-build for my (arm64)
PinePhone from my (amd64) laptop.

$ BUILDER=pbuilder DIST=bookworm git-pbuilder create
$ echo 'PBUILDERSATISFYDEPENDSCMD="/usr/lib/pbuilder/pbuilder-satisfydepends-apt"' > ~/.pbuilderrc
$ BUILDER=pbuilder gbp buildpackage --git-pbuilder --git-pbuilder-options="--host-arch arm64" --git-dist=bookworm

Chatty builds successfully on the PinePhone using git-buildpackage.
