Duplicated arm directory

[valeriangalliat]

Hey,

On master (a73691b) looks like the arm output directory is cloned at different places (probably due to mv destination issues with multiple builds without distclean):

• out/arm
• out/arm/arm
• out/arm/arch/arm

I believe out/arm/arm and out/arm/arch/arm should be deleted. It appears out/arm/arm is ignored by flashing software, and out/arm/arch/arm is installed in /system/arm which is useless to the system and just takes more space (and is a plain duplicate of what's installed in /system anyway).

Also, do you think anything in the out directory should be tracked by Git? I'd rather leave the out directory empty so we begin with a clean build just after cloning.

What do you think?
Thanks!
