Nathan Hjelm fe6528b0d5 opal/atomic: always use C11 atomics if available
This commit disables the use of both the builtin and hand-written
atomics if proper C11 atomic support is detected. This is the first
step towards requiring the availability of C11 atomics for the C
compiler used to build Open MPI.
