From 713224456f4a3242496af803413f670433f27c74 Mon Sep 17 00:00:00 2001

Subject: [PATCH] [PATCH] fix build with uClibc

Fix two build issues with (modern) uClibc:
- uClibc has clock_nanosleep() if built with UCLIBC_HAS_ADVANCED_REALTIME,
  conflicting with emulation function
- uClibc doesn't provide utmpx.h if not built with UCLIBC_HAS_UTMPX, which
  is included in several files (but not needed).
