Are you sure? Many of the autobuilder instances don't have the OpenSSL
development files installed on the host, which means that OpenSSL
support is not enabled in host-python, and crda would fail to build.

I think that a better fix for this problem is to really disable OpenSSL
in Python. Indeed, we shouldn't rely on the system-provided OpenSSL:
OpenSSL has never been part of the Buildroot "core dependencies".

Can we instead disable OpenSSL usage, and then identify (if any) the
packages that needed OpenSSL support from host-python?

Thanks,

Thomas
