- make should be $(MAKE) - add + in front of rules spawning long-lasted make process in a subshell. (This would not be needed with $(MAKE) -C .. target, but our makefiles do not handle that because they use $(PWD)) - split the main 'all' rule as all 4 targets are independant - fix dependencies where appropriate for parallelism Extra, not speed-related changes: - remove some double-colon for targets as they do not need it This cuts build time from 5s to 1.5s on a laptop with -j4, and more importantly from 85s to 35s on a KNL node. As a bonus, the fixed dependencies removes the need to clean before rebuilding all the time. Probably.
