Allow building with GCC >= 13.3 on RISC-V

Allow building with GCC >= 13.3 on RISC-V

Building with GCC was marked as broken on RISC-V in
"46980605309e922d14f646c6705d184cb674c0f7". The patches fixing the issue
with atomic operations were included in the GCC 14 branch and backported
to 13.3.0.

Add the appropriate checks to allow building on RISC-V with the fixed
GCC versions.

Tested with GCC 13.3.0 on a VisionFive 2 board.
