When compiling jailhouse with BR2_PACKAGE_JAILHOUSE_HELPER_SCRIPTS=y,
build is failing with error:
Traceback (most recent call last):

ValueError: Empty module name
This is due to a missing dependency on the target python3 package.
Jailhouse Python scripts are using setuptools with host-python3 which
reads its sysconfig data from the target-python3. See:
https://gitlab.com/buildroot.org/buildroot/-/blob/2024.08.1/package/pkg-python.mk?ref_type=tags#L33
If the target python3 is not installed, this get expanded as an empty
string, leading to this "ValueError: Empty module name" error.
Pure Python packages which are using the python-package infrastructure
usually get this dependency automatically from:
https://gitlab.com/buildroot.org/buildroot/-/blob/2024.08.1/package/pkg-python.mk?ref_type=tags#L295
Here, the jailhouse package rather uses the generic-package
infrastructure, then installs the Python scripts (if enabled) with
dedicated macros. This is why the target python3 is needed.
This commit fixes the issue by adding this missing dependency.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
