File crash-gdb-gnulib-define-warndecl.patch of Package crash

From: Petr Tesarik <petr@tesarici.cz>
Subject: gnulib: Provide a definition of __warndecl 
Upstream: never, compatibility with SLE12 only

The local copy of string.h includes the system string.h. Older glibc makes
use of the __warndecl macro, but gnulib's cdefs.h does not provide one.
