Our Makefile massages the given make arguments to invoke ninja accordingly. One key difference is that ninja will parallelize by default, whereas make only does so with -j<n> or -j. The make man page says that "if the -j option is given without an argument, make will not limit the number of jobs that can run simultaneously". We use to support that by replacing -j with "" (empty string) when calling ninja, so that it would do its auto-parallelization based on the number of CPU cores.
This was accidentally broken at d1ce2cc95b (Makefile: preserve --jobserver-auth argument when calling ninja, 2024-04-02), causing `make -j` to fail: $ make -j V=1 /usr/bin/ninja -v -j -d keepdepfile all | cat make -C contrib/plugins/ V="1" TARGET_DIR="contrib/plugins/" all ninja: fatal: invalid -j parameter make: *** [Makefile:161: run-ninja] Error Let's fix that and indent the touched code for better readability.
