* it was a bit tricky to find this, because
$ bitbake -g lib32-python
$ grep '"python\.' task-depends.dot
doesn't show anything, but if you set
COMPATIBLE_HOST_pn-python = "^(?!x86_64).*"
$ bitbake lib32-python
will fail with:
NOTE: Resolving any missing task queue dependencies
ERROR: Nothing PROVIDES 'python'
python was skipped: incompatible with host x86_64-oe-linux (not in COMPATIBLE_HOST)
ERROR: Required build target 'lib32-python' has no buildable providers.
Missing or unbuildable dependency chain was: ['lib32-python', 'python']
so I was wondering where this dependency was created when it isn't part
of task-depends.dot
in the end I've added small debug output in bitbake:
diff --git a/lib/bb/taskdata.py b/lib/bb/taskdata.py

which showed exactly where the issue was:

* now the fix was simple (the same fix is already in oe-core's python3 recipe,
since https://git.openembedded.org/openembedded-core/commit/?id=02714c105426b0d687620913c1a7401b386428b6)
* and now when I know what task was causing it, it can be shown with bitbake -g as well:
$ bitbake -g lib32-python -c create_manifest

* I've included all these debugging steps, to discuss whether "bitbake -g" should
show also the "optional" tasks - no task from python.do_build depends on
do_create_manifest tasks, it's only called manually with:
bitbake python -c create_manifest
but still bitbake includes this task dependency when preparing runqueue or
maybe bitbake shouldn't include it in the dependency tree when it's not
going to call that task anyway
