[PATCH v3] base.bbclass: Fix matching of MACHINEOVERRIDES in COMPATIBLE_MACHINE

[Otavio Salvador]

When a MACHINEOVERRIDES has more than one value, split by ':' as usual
OVERRIDES, this were not being properly checked in COMPATIBLE_MACHINE
matching as we need to iterate over each SoC family and check if it is
compatible or not.

Changes for v3:
- Stop checking for SOC_FAMILY as it is just for compatibility with
  old BSPs; we move to MACHINEOVERRIDES for this case (RP)

I did run it and it fails. I am fixing it and will send a new  version
well tested.

No variable "compat_machines" exists before this line so this patch
cannot possibly work. What did you test?

We're close to release and I'm getting pushed hard in places like IRC to
take patches like this which clearly don't work :(

I'm not happy.

Cheers,

Richard

I got it when testing, hence my previous e-mail saying I found a problem.
