[Debian-med-packaging] Bug#1063998: bart FTCBFS: rebuilds during dh_auto_install

[Helmut Grohne]

Source: bart
Version: 0.9.00-2
Tags: patch
User: debian-cross at lists.debian.org
Usertags: ftcbfs

bart fails to cross build from source, because it repeforms some of the
compilation and link steps during dh_auto_install where debhelper does
not pass cross tools. These steps fail (due to using the wrong
toolchain). Rather than figure out why it is rebuilding during
dh_auto_install, I suggest exporting all the build tools for all targets
as that's easy to do. I'm attaching a patch for your convenience.
Alternatively, you may change the upstream build system to avoid such
rebuilds at make install time.
