The linker should already catch this case and error out early but just
to be absolutely sure, add a second check here so we don't get an
unexpectedly large epicardium binary which would overlap into pycardium
storage.

Hawkmoth is not yet working with Spinx 3; issue a warning when detecting
a Sphinx 3 environment as the resulting docs will be broken.

The tr hack we used so far has been painful.  The amount of locale
environment variables we need to set is surely a telling sign of that ...

Replace this with objcopy which can do the same thing, but much easier
and without locale related side effects ;)
