Since the test uses __sync_fetch_and_add, add a requirement for
target to support atomic operations on int and long types.
This fixes a spurious test failure on pru-unknown-elf, which lacks
atomic ops. The test still passes on x86_64-linux-gnu.
Pushed to trunk as obvious.

operations on int and long types.
