This issue was reported by Romain [1] when I posted an upgrade from
optee-3.5.0 to 3.7.0 in BR.
Actually, I'm still not sure I really understand the issue since optee-os.mk
already specifies pycrypto as a dependency.

OPTEE_OS_DEPENDENCIES = host-openssl host-python-pycrypto
host-python-pyelftools

Maybe it is an issue related to python versioning (2 vs 3)?
I'll try to have a look in the coming... days, but I quite busy on some
other topics.
Will do my best :|

Regards,
Etienne
