Bug#949990: zita-rev1 FTCBFS: uses a non-standard pkg-config variabel

[Helmut Grohne <helmut@subdivi.de>]

Source: zita-rev1
Version: 0.2.2-1
Tags: patch
User: debian-cross@lists.debian.org
Usertags: ftcbfs

zita-rev1 fails to cross build from source, because it uses a
non-standard variable for pkg-config, which isn't substituted by
debhelper. Thus debian/rules sets PKG_CONF=pkg-config and uses the build
architecture one. Please consider initializing it from e.g. dpkg's
buildtools.mk (this patch) or using the standard name PKG_CONFIG that is
properly substituted by dh_auto_build.
