lib/int_util: My refactoring to allow shared utility code had a fatal flaw when

multiple .a files would end up with duplicate strong definitions. This could
cause link failures in certain scenarios when both definitions got loaded.
- The best solution I see for this (aside from not factoring out the utility
code) is to mark the definitions weak. Better solutions appreciated!
