    Makefile: add distclean target
    
    ...and move tags/cscope removal to it.
    
    'make clean' is traditionally used to remove all
    compiler-generated stuff in order to do a clean rebuild.
    
    'make distclean' cleans more, it is used to prepare sources
    for 'make dist' (creating a source tarball).
    
    It is unfortunate to find out you have to run 'make tags cscope'
    every time after 'make clean'.
