Fix intl/libgnuintl.h

[Masaki Muranaka]

Hello,

An attached patch is for intl/libgnuintl.h based on
the discussion at gdb-patches ML.

_() macro is extracted to intl_gettext() on some
hosts which use libgnuintl.h.
GCC regards some types of gettext call as constant,
but intl_gettext() isn't regarded.
So, the build was failed by error in case compiling
the code that has _() macro with
-Wformat -Wformat-nonliteral -Werror .

The patch is just for avoiding build failure on
GDB / mips64-elf cross target / MacOSX host.
I guess the similar patch should be applied on
other extern prototypes in libgnuintl.h.
(But I didn't. I don't have enough hosts to test.)
