Hi Nadav,
I applied your patch and pushed it. But I am getting now following
warnings from Busybox compile:

Any idea how to avoid this?

Using 64bit time on 32bit targets was only
introduced in Linux 5.1.0.
On versions prior to that, compiling uClibc-ng produces incorrect headers
that cause the `clock_nanosleep` syscall to receive incorrect arguments.
