- We hook into the BR2_PACKAGE_HOST_PYTHON_SSL option, and add
--disable-hashlib in the "else" case of this condition. This makes
the BR2_PACKAGE_HOST_PYTHON_SSL option have the semantic "build all
Python modules that depend on OpenSSL".
- We create a separate BR2_PACKAGE_HOST_PYTHON_HASHLIB option, so that
the semantic of BR2_PACKAGE_HOST_PYTHON_SSL remains "build the
Python ssl module"
- We simply unconditionally add --disable-hashlib like I proposed, and
wait until someone needs hashlib in host-python.
I suggest we take the third solution for now.
