Log:
[CMake] Pass monorepo build settings in cross compile

This allows the cross compiled build targets to configure the LLVM tools and sub-projects that are part of the main build.

This is needed for generating native non llvm *-tablegen tools when cross compiling clang in the monorepo build environment.
