Bug#1063452: tty-clock FTCBFS: hard codes the build architecture pkg-config

[Helmut Grohne <helmut@subdivi.de>]

Source: tty-clock
Version: 2.3-4
Tags: patch upstream
User: debian-cross@lists.debian.org
Usertags: ftcbfs

tty-clock fails to cross build from source, because the upstream
Makefile hard codes the build architecture pkg-config. I'm attaching a
patch that makes pkg-config substitutable. After applying it, tty-clock
becomes cross buildable.
