[Buildroot] [PATCH] package/gnutls: Fix build with uClibc

[stefan at astylos.dk]

From: Stefan Sørensen <stefan.sorensen at spectralink.com>

Since v3.6.14 gnutls wants to use the 'e' flag with fopen to set the
O_CLOEXEC flags. Since this is a glibc extension, it will trigger a
gnulib override of fopen on non-glibc systems, but that override
breaks the uClibc stdio.h header.

Fixes:

+Subject: [PATCH] Fix gnulib stdio.h include on uclibc
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The __need_FILE define used by gnulib interferes with the uClibc stdio.h
+header, so move the inclusion the stdio.h to after __need_FILE has been
+undefined again.
