Package: libgpg-error-dev Version: 1.35-1 IMHO, this package could be Multi-Arch: same, and therefore support cross development easily, if /usr/bin/gpg-error-config were renamed to /usr/bin/<multiarch_name>-gpg-error-config, e.g. /usr/bin/arm-linux-gnueabi-gpg-error-config.
This probably needs a symlink for the native platform or similar to not break existing build processes.
