pycairo cannot be cross built for multiple reason. The immediate failure
is installing the sphinx dependencies. Fortunately, the documentation
already is separated into an Arch:all -doc package, so all we have to do
is move the relevant dependencies to B-D-I to make them irrelevant for
cross building. That happens to include the sphinxdoc debhelper addon,
so I suggest enabling addons via Build-Depends. Then, the host
architecture Python interpreter cannot be installed. Typically, what is
needed for cross building is libpython3-all-dev plus
python3-all-dev:native. Once these changes are applied, it actually
starts building, but the emitted extension uses a build architecture
filename. This is due to using defaulting to the build architecture
sysconfig. If it were being built using pybuild, debhelper would handle
this, but for meson there usually is no need to set this. Hence, we get
to do this manually. I'm attaching a patch handling all of the
aforementioned issues for your convenience.
