Yes.  Your application is a native program, so it only uses build and
host.  DejaGNU is a cross-aware program, so it uses build, host, and
target: build is where dejagnu runs, host is where cross tools run by
dejagnu should run, target is your machine B.  In general, build !=
host for dejagnu isn't worth the trouble.

Also, host_execute doesn't do what you think it does.  You'd want
"remote_exec host" to run programs, and some other mechanism besides
host_execute to decide whether tests pass or fail.  I think
host_execute is just misnamed.
