This uses APIs that are not available on Win7. Since this is a build-time
configuration, and since we can't use the SDK version as an indicator

disabling it, to maintain Win7 support if desired.

Fix the following build failure on 32-bit architectures using 64-bit
time_t (e.g. riscv32):
../src/util/futex.h: In function 'sys_futex':
../src/util/futex.h:39:19: error: 'SYS_futex' undeclared (first use in this function); did you mean 'sys_futex'?
39 | return syscall(SYS_futex, addr1, op, val1, timeout, addr2, val3);
| ^~~~~~~~~
| sys_futex
