Bug#851201: amb-plugins FTCBFS: hard codes build architecture compiler

[Helmut Grohne]

Source: amb-plugins
Version: 0.8.1-6
Tags: patch
User: helmutg at debian.org
Usertags: rebootstrap

amb-plugins fails to cross build from source, because its build system
hard codes the build architecture compiler g++. Making it substitutable
by using $(CXX) makes the cross build succeed, because dh_auto_build
populates $(CXX) with a cross compiler. Please consider applying the
attached patch.
