Backport gnulib fixes for C11. Fixes Savannah bug #37738.

* grub-core/gnulib/stdio.in.h (gets): Warn on use only if
* m4/stdio_h.m4 (gl_STDIO_H): Check for gets.

Compiling grub2 with glibc 2.16 results in a compilation failure due to 'gets' undeclaration:-

x86_64-unknown-linux-gnu-gcc -DHAVE_CONFIG_H -I. -I../.. -I../../intl -MT argp-eexst.o -MD -MP -MF .deps/argp-eexst.Tpo -c -o argp-eexst.o argp-eexst.c
In file included from argp.h:22:0,
from argp-eexst.c:25:
./stdio.h:456:1: error: 'gets' undeclared here (not in a function)


Working solution is to remove line 144 --

_GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");

-- from grub/grub-core/gnulib/stdio.in.h in svn.

Building on Arch Linux.
