[meta-freescale] [meta-fsl-arm][PATCH v3] fsl-dynamic-packagearch: on thumb builds, add MACHINE_SOCARCH arm feed

[Otavio Salvador]

Hello Max,

(I have added some more people to the Cc list as I think this is a
generic problem)

For reference of the source changes, the patch is online[1].

I think when thumb is used, the normal ARM should be added but the
inverse shouldn't be truth as I might want to not use thumb at all.

In any case, I think this should be handled in the generic code which
adds the PACKAGE_EXTRA_ARCHES and not in our class.

Please people, I need your view on this...
