commit: https://git.buildroot.net/buildroot/commit/?id=fa627738266e5c5c45f6250657ac113cc99df5a3
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
host-python3 currently detect if there is an usable OpenSSL installation
and conditionnaly compiles the 'ssl', '_ssl' and '_hashlib' modules.
This may break compilation if the system's OpenSSL has been updated to
1.1.0 because of a bug in python, see https://bugs.python.org/issue26470
for details.
Unlike Python 2.7, Python 3 unconditionnaly compiles fallbacks for
common hash algorithm, so disabling OpenSSL will still leave Python 3
with implementations of common hash algorithm.
This adds a patch to configure.ac patch to implement a --disable-openssl
option.
