Summary: We would like to build a shared library with all fbcode dependencies statically linked within. This resulting .so should not drop any symbols definitions in the building process. To ensure that, we use `link_whole=True` according to https://buck.build/rule/cxx_library.html#link_whole. Since `link_whole` is `False` by default, adding a `link_whole=False` to existing libraries won't change any behavior. Pull Request resolved: https://github.com/facebook/rocksdb/pull/7466 Test Plan: build a .so and test internally.
