[Pkg-gnupg-maint] Bug#736286: gnupg: Patch to make the gnupg cross-build to Windows more resilient

[Stephen Kitt]

Package: gnupg
Version: 1.4.16-1
Severity: wishlist
Tags: patch

Hi,

I figured out the cause of the build failure which led me to file
#730271 - it's the cross-compilation detection. When cross-compiling,
if only --host is specified, autoconf builds a program and attempts to
run it to see if the build is actually a cross-compilation. If
something like binfmt-support allows a Windows binary to run directly
(with help from Wine), autoconf determines that it's not
cross-compiling and the build eventually fails.

The solution is to fully specify the build and host architectures, as
follows:
