Bug#981210: vala: reduce Build-Depends

[Helmut Grohne]

Source: vala
Version: 0.48.13-1
Tags: patch
User: debian-cross at lists.debian.org
Usertags: cross-satisfiability

vala cannot be cross built from source, because it has unsatisfiable
Build-Depends. It also participates in dependency loops relevant to
architecture bootstrap. Rather than look into such difficult problems, I
looked for easily droppable dependencies. At first, it seemed like
help2man was unused, but it turns out that vala degrades to shipping
prebuilt manual pages. I suggest deleting the prebuilt ones to ensure
that they're always generated. The documentation is only needed for
vala-N.NN-doc, which is Arch:all and the build makes building the
documentation optional. As such, docbook-xml and xsltproc can be demoted
to Build-Depends-Indep. The dependencies libdbus-1-dev, dbus and
libgirepository1.0-dev seem to be relevant to unit tests only. They
don't otherwise influence the resulting build artifacts. I therefore
propose annotating them <!nocheck>. Please consider applying the
attached patch.
