While working on SERVER-46296 it was observed that in a normal --link-model=dynamic build that the exported symbols file was inappropriately applied to the embedded shared library even when building in non-SDK mode. The fix developed in code review for SERVER-46296 is to only apply the export file when building in SDK mode. However, the larger work for SERVER-46296 is still blocked on startup performance. This ticket exists to split the fix out from the SERVER-46296 work so we can commit just the fix for this issue.
