Add 32 / 64 bit abi lists to system properties.
Introduce ro.product.cpu.abilist32 / abilist64, which are comma separated lists of the 32 and 64 bit ABIs that the device supports. These properties are used by the zygote and system server to determine what ABI an app should be started with. This changes move abilist related make steps out of envsetup.mk and into config.mk because they depend on variables set by core/combo/***. Additionally, config.mk performs a few additional cleanups of these variables (like stripping them) after the inclusion of envsetup.mk so this seems like a better place to put them. bug: 13647418 Change-Id: I3db39bdd761220c5b4966f651892fb592396f9a1
