    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
