I ran into an issue trying to build the server on my ubuntu1804-workstation with static linking.

scons command:
./buildscripts/scons.py --ninja generate-ninja --modules= --variables-files=etc/scons/mongodbtoolchain_stable_gcc.vars --link-model=static --dbg=on --opt=off ICECC=icecc CCACHE=ccache

then running ninja resulted in this error:

I fixed it by reverting this commit https://github.com/mongodb/mongo/commit/86da2a644b2a7bcb2ad6c0ea463e7ddc8ca6c6ac and then rebuilding.
