You need to make sure that the ihxutil built in
utils/ihxutil/<hostcpu>-<hostos>/ is available in PATH, so that the
compiler will do the conversion.

The text mode IDE can only ever compile for one CPU platform, so you need
to build it for Z80. Though I don't know right now whether this is enabled.
