Subject: Cmake build generator support: build stage

Multi-target architecture implementation:
    each root source code directory presents the one
    *INTERFACE* target to it's subdirectory subtargets
    that link only as *STATIC* library.
    For instance, *arch* directory presents *Architecture* target
    then *Architecture* target has *CPUID*, *IO*, *PORT*
    and etc. dependencies

Exact order of linking targets is: boot.o CRTIBUNDLE <TARGETS> CRTNBUNDLE.
Sequence destruction cause to UB. Please to pay attention to this.

TODO
- Debug information
- Build type
- Toolchain file
- Image creation
- Build by WinGW compiler on Windows platform (optional)
