[LTP] [PATCH] syscalls/stime: Use 3 variants via test_multiplex()

[Xiao Yang]

Hi Steve,

Could you tell me if Android's libc doesn't implements stime()?
If libc stime() isn't implemented on Android, we should avoid testing it
as the patch does.

Best Regards,
Xiao Yang

Hi Xiao, that is correct, bionic (Android libc) does not provide stime().

I reviewed and tested your patch on Android, looks good to me.
