Subject: [PATCH] Ticket 49305 - Need to wrap atomic calls

Bug Description:  Some RHEL 7.5 platforms (ppc 32bit) still do not support
                  all the gcc built-in atomics.  This breaks the downstream
                  builds.

Fix Description:  Use wrapper functions for the atomic's using #define's
                  to detect if builtin atomics are supported, otherwise
                  use the generic nspr atomic functions.
