Usertags: cross-satisfiability
jags cannot be cross built from source, because it depends on g++ and
gfortran. These dependencies refer to the host architecture toolchain
installed for the host architecture. If it were installable, it could
not be run. What is really needed here is a native toolchain for the
host architecture. We may get that by appending a "-for-host" suffix.
That comes with a downside attached though. We may no longer just run
"gfortran" and instead must invoke it as "${DEB_HOST_GNU_TYPE}-gfortran"
even in native builds. dpkg's buildtools.mk may export a suitable F77
environment variable to achieve that. I'm attaching a patch meant for
forky for your convenience.
