<pre>There is no way to backport builtins for architectures that lack atomics at the
ISA level.
On arm/hppa/sh linux has a syscall which the gcc documentation claims can only

Even on Linux with the latest toolchains this should be checked as there are
cases where some or none of the atomics may be present.</pre>
