Bug#960291: dhcpcd-dbus FTCBFS: uses the build architecture pkg-config

[Helmut Grohne <helmut@subdivi.de>]

Source: dhcpcd-dbus
Version: 0.6.0-3
Tags: patch upstream
User: debian-cross@lists.debian.org
Usertags: ftcbfs

dhcpcd-dbus fails to cross build from source, because the upstream
configure script hard codes the build architecture pkg-config. The
attached patch implements a detection method similar to the detection
method for the C compiler and makes dhcpcd-dbus cross buildable. Please
consider applying the patch.
