package/multicat: fix HAVE_CLOCK_NANOSLEEP with uClibc

Browse Source 
multicat uses clock_nanosleep() conditionally if HAVE_CLOCK_NANOSLEEP is
defined. Unfortunatly, multicat does not use autoconf to check if
clock_nanosleep() is really available, but defines it if __APPLE__ is not
defined.

With uClibc clock_nanosleep() is not available if the C library is configured
without NPTL support (sets __UCLIBC_HAS_THREADS_NATIVE__) or
__UCLIBC_HAS_ADVANCED_REALTIME__ is not set.

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.
