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.
