protobuf-c: disable parallelism to avoid race condition
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: https://github.com/protobuf-c/protobuf-c/pull/340 Signed-off-by: Paul Eggleton <paul.eggleton@linux.microsoft.com> Signed-off-by: Khem Raj <raj.khem@gmail.com> (cherry picked from commit 3251fe210a91d13ab2a6c5b7ecb283aa8e019020) Signed-off-by: Armin Kuster <akuster808@gmail.com>
