Only if you choose to use weakexternal with a set default symbol for 
dynamic linking. I personally don't think that's a good idea in many cases.

This change doesn't require you to to set the default symbol, and if you 
don't it'll work like a normal weakexternal reference(eg. be nil and not 
warn you if it's undefined)
