[multicat-devel] [PATCH] Fix HAVE_CLOCK_NANOSLEEP with uClibc

[Jörg Krause]

uClibc may be configured without support for clock_nanosleep(). The
function is
only available with uClibc if the C library is build with NPTL support
(sets
__UCLIBC_HAS_THREADS_NATIVE__) and __UCLIBC_HAS_ADVANCED_REALTIME__
set.
