Bug#1078010: libnet-z3950-zoom-perl FTCBFS: hard codes the build architecture pkg-config

[Helmut Grohne]

Source: libnet-z3950-zoom-perl
Version: 1.32-1
Tags: patch
User: debian-cross at lists.debian.org
Usertags: ftcbfs

libnet-z3950-zoom-perl fails to cross build from source, because
Makefile.PL hard codes the build architecture pkg-config and thus fails
finding yaz, which is only requested for the host architecture. There is
no really good mechanism to solve this at the time of this writing, but
making pkg-config substitutable via the environment variable PKG_CONFIG
and correctly substituting it is common in other build systems. I'm
attaching a patch for your convenience. If you see a way to derive the
toolchain prefix from the perl configuration module, that would be a
better way.
