This patch removes the arch-specific atomic instruction, relying on compiler builtins. The __sparc32_atomic_locks support is removed and a configure check is added to check if compiler uses libatomic to implement CAS. It also removes the sparc specific sem_* and pthread_barrier_* implementations. It in turn allows buidling against a LEON3/LEON4 sparcv8 target, although it will still be incompatible with generic sparcv9. Checked on sparcv9-linux-gnu and sparc64-linux-gnu. I also checked with build against sparcv8-linux-gnu with -mcpu=leon3. Tested-by: Andreas Larsson <andreas@gaisler.com>
