[Buildroot] How to avoid rebuilding host-cmake

Hi all,

I am trying to reduce the amount of time it takes to rebuild the linux kernel and its dependencies.  I am already using the external toolchain option (toolchain was originally built using buildroot, but in an external directory) so I’m not rebuilding the toolchain unnecessarily. However, for some reason after doing ‘make clean’, host-cmake has to be rebuilt. For my configuration host-cmake is the most time consuming part of the build.

Is there a way that I can avoid having to rebuilding host-cmake after doing a make clean?
