Currently Haiku does not support add-ons with undefined weak symbols: it
reports that a symbol could not be resolved and does not load the add-on.
As I understand it, undefined weak symbols should not be looked up, but
just mapped to 0
http://www.delorie.com/gnu/docs/binutils/binutils_4.html
The symbol is a weak object. When a weak defined symbol is linked with a
normal defined symbol, the normal defined symbol is used with no error.
When a weak undefined symbol is linked and the symbol is not defined, the
value of the weak symbol becomes zero with no error.

"Unresolved weak symbols have a zero value".
