I build Hiawatha regularly for ARM on x86_64 and have encountered no 
issues like the one you have found. Could you check the following for me 
please:

1) Are you using the latest oe-core
2) Have you changed the recipe in anyway
3) What architecture are you building for

If you satisfy all of these then I would suggest you drop Hugo and email 
who is the Hiawatha developer, his email can be found on the Hiawatha 
website. He is fairly friendly and usually responds to querys quickly.

Regards,
Jack.
