make: drop all system tests

 # Notes:
 #
 # This is all roughly based on the Makefile system used by the Linux
 # kernel, but is a non-recursive make -- we put the entire dependency
 # graph in front of make and let it figure it out.
 #
 # The code below generates a separate .mk file for each target, but
 # all are sourced by the top-level Makefile.  This means that all
 # variables in .mk-files clobber one another.  Be careful to use :=
 # where appropriate for immediate evaluation, and similarly to watch
 # that you're not relying on a variable value to last beween different
 # .mk files.
 #
 # TODOs:
 #
 # Global settings and utility functions are currently stuffed in the
 # toplevel Makefile.  It may make sense to generate some .mk files on
 # the side to keep the the files readable.
