When we copy the whole boost-root AFTER the build(s) it will contain
also build artefacts such as the bin.v2 folder.
When restoring that later B2 might skip parts of the build although it
should not.
Make a copy after the initial setup & bootstrap.
- Deduce PACKAGES from CXX/B2_COMPILER
- Deduce B2_TOOLSET from B2_COMPILER
- Write the correct user-config.jam in common_install.sh
- Print compiler location and version in common_install.sh
