Retry building might success.
Maybe we can upgrade to higher version leveldb

Occasionally occurring error, and probably because Makefile is not very good, has bugs when we use make -jx.
If it's really bugging us, I agree with upgrading higher level. We also can disable shared lib building to save time.
