Bug#922538: cultivation FTCBFS: performs a native build

[Helmut Grohne]

Source: cultivation
Version: 9+dfsg1-2
Tags: patch
User: helmutg at debian.org
Usertags: rebootstrap

cultivation fails to cross build from source, because it does not pass
any cross tools to make. The easiest way of doing so - using
dh_auto_build - does not quite fix that, because cultivation uses an
uncommon name for the C++ compiler "GXX". After renaming the compiler,
it cross builds successfully. Please consider applying the attached
patch.
