[OpenWrt-Devel] [PATCH] odhcp6c: fix compilation with musl 1.2.0

[Rosen Penev]

SYS_clock_gettime is gone with musl 1.2.0. Switch to using the normal
function.

This was done back in the day when uClibc was used when librt was
separate. Since only glibc is impacted now, this should be fine.

Added a link to rt just to be sure.
