Indeed I was looking into Kconfig documentation and found something similar.
However there's an anti-dependency. It is enabled by default and can only be
disabled with $(cc-option,-mno-unaligned-access)
So guess we will have to change  ARC_USE_UNALIGNED_MEM_ACCESS to
ARC_*LACKS*_UNALIGNED_MEM_ACCESS

I'll tinker a bit and post an update soon.
