Mark internal stdlib functions with attribute_hidden [BZ #18822]
Mark internal stdlib functions with attribute_hidden to allow direct
access within libc.so and libc.a without using GOT nor PLT.  __realpath
is hidden with libc_hidden_proto and libc_hidden_def since the exported
realpath is an alias of __realpath.
