    build: run targets cscope,tags,... using tree-wide approach
    
    Despite being a matter of taste, in general, there are two main approaches
    when dealing with code tagging: tree-wide, where all the sources are taken
    into account or config-wide, when considering Kconfig options and actually
    built files. At the moment, all_sources variable is defined using SUBDIRS,
    which lists all the directories except arch/, where only $(TARGET_ARCH)
    is taken into account. This makes it difficult to reason about and creates
    fuzzy boundaries being a blocker when considering new directories that
    might be config-dependent (like crypto/ which is missing in SUBDIRS).
    
    For now, switch to the intermediate solution to list all the directories
    in SUBDIRS without exceptions (also include crypto/). This way, the
    approach taken is clear allowing new directories to be listed right away
    without waiting to fix the infrastructure first. In the future, we can
    then add support for config-wide approach.
