    Description

      It is handy sometimes to be able to run patch builds that don't use the shared SCons cache, for instance to A/B test the performance impact of a compiler option or a toolchain change.

      The easiest way to do this is to build with evergreen patch -param patch_compile_flags=-cache-disable .... Unfortunately, this appears to be broken right now, probably due to our cachedir customizations.

      The stack trace looks like:

      [2021/11/03 01:25:33.555] scons: *** [build\cached\mongo\config.h] TypeError : stat: path should be string, bytes, os.PathLike or integer, not NoneType
