Current builds of the mongo_csfle_v1 shared library are pulling in libsasl2.so/dll as a DT_NEEDED dependency, which is unnecessary. There should be a way to tell scons to exclude sasl2 when building the shared library. Something like --use-sasl=none, modeled after --js-engine=none.

Edit: per the conversation below, we can accomplish this task by simply adding --enterprise-features=fle to the scons flags when building the csfle shared library.
