It looks like some parts of the build process respect the set parallelism via NINJAFLAGS, some don't. I still see ~16-20 processes being spawned to compile or generate stuff sometimes (e.g. with moc). However, it is still an improvement compared to not setting NINJAFLAGS at all.

Let's see if my build passes.

This doesn't look like an issue introduced with this PR...
Seems like I triggered an internal assertion in GCC: https://github.com/gcc-mirror/gcc/blob/2123635378d32d884c8ebfa5d01c8006b24ff54f/gcc/ggc-common.cc#L382C1-L382C23

For some reason, entering the environment generated by EB, and running the same ninja command worked fine. Don't know why I ran into this issue...
