Currently we build-depend on the native python (via asciidoc), and on
the host python (via python-dev). As these are not coinstallable it
is impossible to perform a complete cross-build. Until that's resolved,
this will allow cross-building of most of the package with the
combination of the 'cross' and 'nopython' profiles.
(This also sidesteps the issue of perf wanting a multilib compiler.)
* Drop redundant gitignore.patch from linux-tools
* Rename linux-tools' debian/templates/control.main.in to
debian/templates/control.tools.in
* Combine changelogs, putting all entries for each upstream release
cycle in chronological order
* Combine rules and gencontrol.py code
