H.J. Lu 67c0579669 Mark _init and _fini as hidden [BZ #23145]
_init and _fini are special functions provided by glibc for linker to
define DT_INIT and DT_FINI in executable and shared library.  They
should never be put in dynamic symbol table.  This patch marks them as
hidden to remove them from dynamic symbol table.

Tested with build-many-glibcs.py.
