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.

This patch merges the latest release of gettext into the intl
subdirectory. The initial motivation was to include the plural.y
changes which enable building with bison 3.0, but the majority
of the other changes are merely cosmetic so it seemed like merging
the whole directory was simpler than trying to take it piecemeal.
The merge was done by copying across the latext gettext code and
adding in a few small glibc changes that have been added over the
years that seemed beneficial, as well as a couple of small build
fixes that should be merged back to gettext. I also reverted the
gettext commit:
commit 279b57fc367251666f00e8e2b599b83703451afb
Author: Bruno Haible <bruno@clisp.org>
Date: Fri Jun 14 12:03:49 2002 +0000
Make absolute pathnames inside $LANGUAGE work.
As it caused localedata/tst-setlocale3 to fail and it wasn't clear
that glibc wanted that behaviour.
The merge has dropped many uses of __glibc_likely/unlikely. This is
intentional given that it eases merging. It seems to me that the cost
of continually rewriting these lines when merging and the risk of adding
bugs when doing so outweighs the benefits of using these macros when
code is shared with another project.
Tested with make check on x86_64.
ChangeLog:
2014-12-11 Will Newton <will.newton@linaro.org>
