Bug#900887: ir.lv2 FTCBFS: uses build architecture build tools

[Helmut Grohne]

Source: ir.lv2
Version: 1.3.3~dfsg0-1
Tags: patch
User: helmutg at debian.org
Usertags: rebootstrap

ir.lv2 fails to cross build from source, because it uses build
architecture build tools. The attached patch makes ir.lv2 cross
buildable. It fixes both the upstream build system to make build tools
substitutable as well as teaching debian/rules to pass the required
tools. Please consider applying it.
