newer 32bit arches e.g. RV32 and ARC do not have __NR_io_getevents syscall and have started of with 64bit time_t so there is no 32bit version Signed-off-by: Khem Raj <raj.khem@gmail.com>

Use SYS_futex for syscall
|
|
|
|
glibc defines SYS_futex and on newer 32bit CPUs like RISCV-32, arc there
|
|
is no 32bit time_t therefore define SYS_futex in terms of SYS_futex_time64
