re PR libstdc++/5198 (3.0.3 linux x m68k build fail: invalid opcodes in c++locale.cc) 

        PR libstdc++/5198
        * config/cpu/m68k/bits/atomicity.h (__exchange_and_add): Only use
        CAS on the cpu variants that support it.  Add versions that use
        TAS and that disable interrupts.
        (__atomic_add): Use __exchange_and_add to guarantee atomicity.
