This is covered in build(7), one of the manpages in the 
very-useful-but-not-very-obvious category (along with ports, hier, security 
and tuning IMO (all of which are also in section 7 of the manual..))

Anyway, it's
 make -DBATCH_DELETE_OLD_FILES delete-old
 make -DBATCH_DELETE_OLD_FILES delete-old-libs
