Unfortunately 489d3b4b932ee8016d792341f8ea5836a9522cd4 did not completely
fix the problem - if you try cleaning and rebuilding protobuf-c-native it
doesn't take long to reproduce the issue on a 32-core machine. I spent
some time trying to debug this but failed, there is still a race between
generating t.test-full.pb.h and compiling cxx_generate_packed_data.c
despite BUILT_SOURCES and explicit dependencies. I even tried converting
the multiple target rules to use grouped targets (&:), that didn't fix it
either. Disabling parallelism as a workaround only costs ~20s and it
turns out that upstream is switching to Meson soon anyway:
