Make __tunables_init hidden and avoid PLT
Since __tunables_init is internal to ld.so, we should mark it hidden to avoid PLT. We should also avoid PLT when calling __tunable_set_val within ld.so. 2017-05-25 Siddhesh Poyarekar <siddhesh@sourceware.org> H.J. Lu <hongjiu.lu@intel.com> * elf/dl-tunables.c (__tunable_set_val): Make a hidden alias. * elf/dl-tunables.h (__tunables_init): Mark it hidden in rtld. (__tunable_set_val): Likewise.
