Hmm, I see:
for subdir in $$list; do \
echo "Making $$target in $$subdir"; \
....
This is a loop over subdirectories. So you can do main target in
parallel with dvi target, but subdirectories run sequentially.
I would put this in a diffent way: you have two rules which invoke
make of main target in src subdirectory. The first is the recursive
rule, the second one is via src stamp. Currently the second rule
can only fire after the first run has finished. But if you allow
both rules to run in parallel then you will get a mess in src.
