Subject: [PATCH v2] deb-pkg: Simplify architecture matching for cross building
No point in invoking dpkg to get the archticture of the host
we build on. Instead directly use the logic implemented
in create_package(). No need anymore to override arch.
While at it fix the linux images to be for the specific
built arch.
