mujs fails to cross build from source. The reason is using the build
architecture compiler in a linker step and then failing to find a
library that is only requested for the host architecture.
Stepping back, that linker invocation happens during dh_auto_install.
debhelper does not pass cross tools to dh_auto_install as it expects
the build to be complete at this point. So the real issue is that part
of the build is performed at dh_auto_install time. It turns out that the
default target performs a debug build while the install-shared target
needs a release build and these builds differ in build product paths.
Once telling dh_auto_build to perform a release build, it actually
builds what is needed for dh_auto_install and that also fixes the cross
build. I'm attaching a patch for your convenience.
