This is meant to support scenarios in which we need to build as little as LLVM as possible for performance reasons (e.g. when enabling LTO). While LLVM CMake build system offers options in this sense, in our investigation they turned out not to be suitable, since either they are not granular enough (`LLVM_INCLUDE/BUILD` flags) or they require active opt out for any new tool added (`*_BUILD_*_TOOL` flags) When using this mechanism, there is the possibility to specify different targets to use for cross-compile hosts.
