This allow to easy reuse of binary packages among similar SoCs. The usual use for this is to share SoC specific packages among different boards. The class can be used to share GPU packages for i.MX53 boards (as all them share the AMD GPU) and i.MX6 based boards (as all them share Vivante GPU).
It inspects the database and identify if the package provides or depends on one of subarch provided values and if it does, it sets the PACKAGE_ARCH for MACHINE_SUBARCH value otherwise if it matches in the machine specific filter, it sets it to MACHINE_ARCH.
