Bug#900194: bluemon FTCBFS: fails finding dbus-1.pc with the build architecture pkg-config

[Helmut Grohne <helmut@subdivi.de>]

Source: bluemon
Version: 1.4-7
Tags: patch upstream
User: helmutg@debian.org
Usertags: rebootstrap

bluemon fails to cross build from source, because the upstream build
system hard codes the build architecture pkg-config and thus fails
finding dbus-1.pc, which is only requested for the host architecture by
Build-Depends. I think the proper solution is to make pkg-config
substitutable. After doing so, bluemon cross builds successfully,
because dh_auto_build substitutes PKG_CONFIG. Please consider applying
the attached patch.
