This can be worked around by :

But still the IAT remains NULL. I suspect that the code that Kai also
patched in ld/emultempl/pep.em and scripttempl/armcoff.sc and
scripttempl/pep.sc might be related.
Can anyone tell me how to interpret the ld scripts ? I haven't the
faintest idea of how they work.
