+[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).
