[Buildroot] [PATCH 1/1] boot/optee-os: Depend on host-python3

[DO]

Hi Thomas,

Good question! The hashbangs in all their Python scripts
use "/usr/bin/env python3" but that's about as much build-time
enforcement there is on Python 3. The maintainers seem happy about
the upstream patch which enable more explicit control of the specific
interpreter used.

Addressed this in the new v2 series.

Addressed this in the new v2 series.

I marked this patch as superseded in Patchwork.
