From 1ac8a6df9a8ad749e40c5a0f21cd75906a3bcff9 Mon Sep 17 00:00:00 2001 From: Anton Hansson Date: Mon, 5 Feb 2018 12:24:12 +0000 Subject: [PATCH] Add a base makefile for 64 bit only builds. This makefile specifies a configuration that only starts a 64 bit zygote (as opposed to both 64/32, as standard 64 bit builds do). It should be inherited by products that only supports 64 bit apps.
