[pkg-gnupg-maint] Bug#933713: libgpg-error-dev: make package fit for cross development

[Francois Gouget]

Package: libgpg-error-dev
Version: 1.36-7
Followup-For: Bug #933713

libgcrypt is under consideration for use in Wine but Wine depends on
proper multiarch support since we need to support both 32 bit and 64 bit
Windows applications (even 64 bit Windows applications have 32 bit
installers).

This means a Wine developer needs to install both the i386 and amd64
variants of libgcrypt-dev which in turn depends on libgpg-error-dev.
Some libgpg-error-dev's lack of multiarch support prevents Wine from
using libgcrypt.

The only blocker for making libgpg-error-dev Multi-Arch: same is
gpg-error-config. However gpg-error-config is not needed on Debian
since there is no need for -I or -L directives; and it has been 
superseded by gpgrt-config and pkgconfig anyway.

So I think it is reasonable to stop shipping gpg-error-config, just like
FreeType stopped shipping freetype-config to become multiarch-compatible.

The attached patch modifies libgpg-error-dev accordingly. Feel free to
incorporate it into a future release and to adjust the changelog as you
see fit.

In the meantime one can generate multiarch-ified packages as follows:
(you'll probably need to create a 32 bit chroot with debootstrap+schroot)
