Wasn't the intention of adding bz2 support to the host python?

But anyway, the fact that BR2_PACKAGE_PYTHON_BZIP2 is enabled or not
should not influence the host-python build. BR2_PACKAGE_PYTHON_BZIP2
is here to configure the target python, not the host one. We presently
don't have a good way to provide configuration options for host
packages.

So your patch should presumably just:

 * Remove the --disable-bz2 line from HOST_PYTHON_CONF_OPT, as you did,
   and replace it with --enable-bz2.

 * Outside of any ifeq condition, do HOST_PYTHON_DEPENDENCIES +=
   host-bzip2.

That will mean that everybody building host-python will have to build
host-bzip2 and the bz2 support in Python, but I think it's OK.

Thanks,

Thomas
