llvm: use ATOMIC64_DEPENDS

Browse Source 
The libraries depend on libatomic on every architecture, link it only
on mips through an open-coded LDFLAGS addition, and still name the
removed arc architecture in their dependencies. ATOMIC64_DEPENDS
restricts the dependency to the targets whose compiler calls libatomic
for 64-bit atomics, and the link flag follows the same symbol, which
also covers the ARMv5 targets.
