• ./bootstrap: Format build/pkgs/SPKG/distros/ information to produce the apt-get/yum command lines shown in the installation manual #26964 now creates documentation files during bootstrap
• make distclean blows away these generated files
• subsequent make fails when building documentation

This ticket fixes it by deleting the generated files in bootstrap-clean instead of misc-clean.
