Here's the bug, I've seen this before, it seems random when it happens 
and changing a few lines can make it go away. Something to do with lto...

main.o swampd-util.o  ./.libs/libswampd.a -lstdc++fs -lphosphor_logging 
-lsdbusplus -lsystemd -lphosphor_dbus

What platform is gsj? We're currently behind tip, and it'll probably 
take me some time to catch up to be able to try anything this new.
