Subject: [PATCH] arm: clean up build variables
Date: Wed, 20 Jan 2016 15:47:59 -0600	[thread overview]
Message-ID: <1453326479-19885-1-git-send-email-cardoe@cardoe.com> (raw)

This consolidates some of the different variables used for the ARM
builds. This change was prompted by the Kconfig changes but looking back
in time the CONFIG_ARM_{32,64} variables existed before Kconfig so this
should just be a generic cleanup.
