From 39042d7f7c4997af55474ebe4513c81f00732837 Mon Sep 17 00:00:00 2001
From: Rosen Penev <rosenp@gmail.com>
Date: Sat, 24 Aug 2019 15:01:16 -0700
Subject: os_sleep: Use nanosleep for POSIX versions 2008 and higher
uClibc-ng optionally disabled deprecated POSIX functions like usleep,
causing compilation failures. This switches to nanosleep while retaining
support for older libcs that do not support nanosleep.
