Bug #16774: Don't require sub-word atomics

• Status: Closed

• Backport: 2.5: REQUIRED, 2.6: DONE, 2.7: DONE

[schwab (Andreas Schwab)]

On some architectures (like RISC-V) sub-word atomics are only available
when linking against -latomic, but the configure script doesn't do that,
causing the atomic checks to fail and the resulting ruby binary is
non-functional. Ruby does not use sub-word atomic operations, rb_atomic_t
is defined to unsigned int, so use unsigned int when checking for atomic
operations.
