When python3 -m build is invoked during host-compile, it fails with:
/builder/staging_dir/hostpkg/bin/python3.14: No module named build
The package's HOST_BUILD_DEPENDS only pulled in python3 and
python-packaging, missing the actual host tooling for the new
pyproject build flow:
- python-build : provides the 'build' module itself
- python-installer : installs the resulting wheel
- python-wheel : wheel format support
- python-flit-core : marshmallow's declared build-backend
(build-backend = "flit_core.buildapi" in
pyproject.toml)
