cmigemo fails to cross build from source. It actually completes
dh_auto_build successfully. Then as dh_auto_build runs, it considers the
"dirs" target out of date and recompiles stuff as a result. Since dh_auto_install does not pass cross toolchains that unnecessary
compilation step fails.

The use of the dirs target has two problems. For one thing, dirs never
exists and therefore always is out of date. I propose removing the
target and depending on the relevant directories (via a variable)
directly. Then, those directories change all the time, so we should turn
them into order-only dependencies to avoid excessive rebuilds. Once
doing both, cmigemo cross builds again. This also speeds up the native
build.

Please consider applying the attached patch and also forwarding it
upstream.
