H.J. Lu 34a87bb07a ld: Hide symbols defined by HIDDEN/PROVIDE_HIDDEN
There should be no difference in output for symbols defined by HIDDEN
or PROVIDE_HIDDEN assignments whether they are explicitly marked as
hidden or not.  This patch adds a new BFD function, bfd_link_hide_symbol,
to hide symbols defined by HIDDEN and PROVIDE_HIDDEN assignments.
