Bug#1152212: coturn FTCBFS: uses the build architecture pkg-config

[Helmut Grohne]

Source: coturn
Version: 4.18.0-1
Tags: patch
User: debian-cross at lists.debian.org
Usertags: ftcbfs

coturn fails to cross build from source, because it uses the build
architecture pkg-config and fails location dependencies as a result. It
has a hand-written configure script that somehow manages to figure out
the correct CC, but it uses the non-standard PKGCONFIG variable for
pkg-config when much of the rest of the world uses PKG_CONFIG.
Reexporting it under the other name fixes the cross build. Please
consider applying the attached patch.
