It cuts dependencies in sense of C++ but add dependencies on module
level. Now to drop old target or add new one you need to change the
code in many places. Moreover now "elf core" knows about kind of
relocations of all targets.

By the way, the initial idea was to reduce code duplication. I missed
the moment when the main target becomes reducing of dependencies.

As to me if we really want to apply this practice from Effective C++
here, let's introduce isXXXDynamicRelocation() functions where XXX is
a target name and call these functions from the main
isDynamicRelocation() routine. This does not make the code better but
allows us to follow the practice ;)
