Ok. When you say "whole", you say that you also "package" what the
toolchain installs, and create a complete sysroot from scratch for each
package being built, including for the toolchain libs/headers ?

Again, when you say "whole", you also separate in multiple host dirs
whatever is installed by each package, and then create a custom
host dir when each package is being built, containing only the
dependencies that it needs?
