Fix build on riscv32
riscv32 fails to build because __NR_futex is not defined on this
architecture:

thread/qfutex_p.h:116:30: error: '__NR_futex' was not declared in this scope; did you mean '_q_futex'?
116 | int result = syscall(__NR_futex, addr, op | FUTEX_PRIVATE_FLAG, val, val2, addr2, val3);
| ^~~~~~~~~~
