[PATCH] automation: set architecture in docker files

[Roger Pau Monne <roger.pau@xxxxxxxxxx>]

Pass the desired architecture of the image in the FROM instruction if the
image is possibly multi-platform.

This allows using the x86 Dockerfiles on OS X on arm64 hardware.

No functional change intended.

I haven't touched the Yocto dockerfile because I'm not sure how it's used.
