looks it does, but I can't get it to work. I get things like:

[hanwen@localhost mf]$ make clean ; make -j1000 out/emmentaler-20.otf
..
Making mf/out/feta-flags20.log < mf
Making mf/out/feta-alphabet20.log < mf
..
Done making mf/out/feta-flags20.log < mf
Making mf/out/feta-flags20.lisp < log
Done making mf/out/feta-alphabet20.log < mf

    autolines, deps = read_log_file (fn)

    str = open (fn).read ()
FileNotFoundError: [Errno 2] No such file or directory:

make: *** [GNUmakefile:132: out/feta-flags20.lisp] Error 1

the $(UPDATE_TARGET) hack works if I compile with -j1000.
