-Subject: [PATCH] Don't require sub-word atomics
-
-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.
