Yeah, thanks for spotting. I fixed that.

I've also added a couple of notes/TODOs to the code

a/ Add support for DEB_BUILD_OPTIONS="parallel=N"?
By default ninja runs N jobs in parallel, where N is derived
from the number of CPUs.
Should this be only done for the build step or install and test as well?
In the latter case, the code to run buildcmd should be factored out.
Or do we just keep ninja's default behaviour and don't bother setting -j
manually.

b/ Add support for DH_QUIET, i.e. don't run with ninja -v in quiet mode.

c/ The install target mangles $ENV to set DESTDIR, which is a bit meh.
Should we save and restore $ENV?

Input welcome.

In theory, meson does support cross building
https://github.com/mesonbuild/meson/wiki/Cross-compilation

I personally do not have experience with it though. So I would need help
with implementing that or leave that to someone else. I wouldn't make
this a blocker though, for merging meson/ninja support.

Regards,
Michael
