H.J. Lu 8bcdb7e0c5 Mark internal functions with attribute_hidden [BZ #18822] 
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.

Size comparison of libc.so:

On x86-64:
        text	   data	    bss	    dec	    hex
Before: 1728577	  20584	  17088	1766249	 1af369
After : 1728593	  20584	  17088	1766265	 1af379

The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.

On i686:
        text	   data	    bss	    dec	    hex
Before: 1869039	  11444	  11112	1891595	 1cdd0b
After : 1868635	  11444	  11112	1891191	 1cdb77

The code size is decreased by avoiding GOT/PLT for hidden functions.
