Bug#1003761: libxml-libxml-perl FTCBFS: uses the build architecture pkg-config

[Helmut Grohne]

Source: libxml-libxml-perl
Version: 2.0207+dfsg-1
Tags: patch
User: debian-cross at lists.debian.org
Usertags: ftcbfs

libxml-libxml-perl fails to cross build from source, because
debian/rules hard codes the build architecture pkg-config. Seeding it
from dpkg's buildtools.mk fixes the build. Please consider applying the
attached patch.
