I'm satisfied with testing that the invocations of this macro in GNU gettext
produce, in 'configure', exactly the expansion that I would expect.

If you want to contribute a unit test for it, feel free to do so.

Yes, for adding a unit test module, adding a module file like the one
you showed is the first step.

Note: The configure.ac-early section is not needed here, since
gl_BUILD_TO_HOST_INIT is already AC_REQUIREd.
