Hide internal __tcgetattr function [BZ #18822]
Hide internal __tcgetattr function to allow direct access within libc.so and libc.a without using GOT nor PLT. [BZ #18822] * include/termios.h (__tcgetattr): Add libc_hidden_proto. * sysdeps/unix/bsd/tcgetattr.c (__tcgetattr): Add libc_hidden_def. * sysdeps/unix/sysv/linux/tcgetattr.c (__tcgetattr): Likewise. * termios/tcgetattr.c (__tcgetattr): Likewise.
