Could you give some more details about this? The tarfile module seems
to only import the bz2 module when a bzip2-compressed file is handled.
Is this actually the case with rust?

I am hesitant between applying your patch (and therefore removing
package/nodejs/0.10.45/0001-remove-python-bz2-dependency.patch), or
adding an hidden BR2_HOST_PACKAGE_PYTHON_BZIP2 that the rust package
could select to make sure bzip2 support is built into host-python.

Indeed, host-python is used by numerous packages, and we're trying to
not add too many dependencies to host-python. On the other hand,
building bzip2 is pretty fast, so maybe it's reasonable to add it as a
mandatory dependency of host-python.
