Bug#888033: alure FTCBFS: does not pass cross flags to cmake, uses plain cc

[Helmut Grohne]

Source: alure
Version: 1.2-6
Tags: patch
User: helmutg at debian.org
Usertags: rebootstrap

alure fails to cross build from source, because it does not pass cross
flags (such as -DCMAKE_SYSTEM_PROCESSOR) to cmake. The easiest way of
doing that is letting dh_auto_configure do it. Further down the build
fails to create an object file consumable by dpkg-shlibdeps, because it
uses the build architecture compiler "cc". Switching to a host tool
fixes the build. Please consider applying the attached patch.
