I've only hit this a few times with MAKEOPTS=-j32 -l32.

I'm going to try hit it with make --shuffle to get a seed. Full log attached: build.log.gz.

Bingo!

bpf-unknown-none-ld: cannot open output file /var/tmp/portage/dev-debug/dtrace-9999/work/dtrace-9999/build/dlibs/bpf_dlib.o: No such file or directory

I can hit it with make --shuffle=3005207791 -j32 -l32 TRIGGERS=.
