Subject: [PATCH] libdirect: define __NR_futex on 32bit architectures using
 64-bit time_t

Newer 32bit architectures like RISCV32 and ARC are using 64bit time_t
from the get go unlike other 32bit architectures, therefore aliasing
__NR_futex to __NR_futex_time64 helps avoid the below errors :

system.c:242:21: error: '__NR_futex' undeclared (first use in this function)
  242 |      ret = syscall( __NR_futex, uaddr, op, val, timeout, uaddr2, val3 );
      |                     ^~~~~~~~~~
