Hide internal __sched_setparam function [BZ #18822]
Hide internal __sched_setparam function to allow direct access within libc.so and libc.a without using GOT nor PLT. __GI___sched_setparam is defined when sysdeps/unix/syscalls.list is used to generate sched_setparam. Otherwise libc_hidden_def is needed explicitly. [BZ #18822] * include/sched.h (__sched_setparam): Add libc_hidden_proto. * posix/sched_setp.c (__sched_setparam): Add libc_hidden_def.
