Subject: kbuild: move "checkthumb" to ARM archprepare
X-Git-Tag: v2014.04-rc2~12
X-Git-Url: https://git.kernelconcepts.de/?p=karo-tx-uboot.git;a=commitdiff_plain;h=388b2e520b07cc857c03a152fc6006763f78b9d6

kbuild: move "checkthumb" to ARM archprepare

"checkthumb" makes sense only for ARM architecture.
Move it to arch/arm/config.mk.

To make sure gcc supports THUMB mode before beginning build,
run "checkthumb" during "archprepare".
