GNU Make from version 4 onwards has a way to control how the output
streams from parallel jobs get displayed. I think all you're seeing is
that several jobs are printing to stdout at the same time and their
output streams are getting mixed up (which is the default behaviour),
but you can control exactly when they get printed with the option -O (or
--output-sync) as described here:

https://www.gnu.org/software/make/manual/html_node/Parallel-Output.html#Parallel-Output

Using 'make -j4 -O' is probably the simplest solution.
