New java 11 on latest Ubuntu calls sysconf to get value
of _SC_THREAD_STACK_MIN parameter to inquire about minimal
stack size and crashes when gets -1 from OSv. This patch
makes sysconf() return the same value Linux returns.
Similarly one of the libraries libtsm.so used by cli
needs value of _SC_LINE_MAX and this patch makes sysconf
handle this parameter as well.
