Subject: [PATCH] libntp: Do not use PTHREAD_STACK_MIN on glibc

In glibc 2.34+ PTHREAD_STACK_MIN is not a compile-time constant which
could mean different stack sizes at runtime on different architectures
and it also causes compile failure. Default glibc thread stack size
or 64Kb set by ntp should be good in glibc these days.
