Subject: Allow overwriting the path to pkg-config
Author: Helmut Grohne <helmut@subdivi.de>
Forwarded: https://github.com/florentc/xob/pull/52
Bug-Debian: https://bugs.debian.org/1120810
During cross-compilation, it may be necessary to use a different pkg-config
than the one for the build architecture. Using a Makefile variable allows
substituting the pkg-config with the one from the host architecture.
