Bug#840309: brltty: FTBFS in testing (No rule to make target '-lsystemd)

[Santiago Vila <sanvila@debian.org>]

Package: src:brltty
Version: 5.3.1-3
Severity: serious

Dear maintainer:

I tried to build this package in stretch with "dpkg-buildpackage -A"
(which is what the "Arch: all" autobuilder would do to build it)
but it failed:

The relevant part of the build log is included above.
(If you need a full build log, just say so).

If this is really a bug in one of the build-depends, please use reassign and affects,
so that this is still visible in the page for this package.

Thanks.
