Subject: ARC: Disable CONFIG_ARC_HAS_ATOMICS in uClibc if building without
 -matomics

In case we build for ARC core which has no support of atomic ops among
other things we need to configure libc to use Linux kernel helper to emulate
HS atomic ops. This is done with disabling of CONFIG_ARC_HAS_ATOMICS in uClibc.

Currently we __remove__ this option from .config but this makes no sense as
its default state is "y" so we need to explicitly disable it instead.
