Summary: Fixed xfunc related compile errors in ROCKSDB_LITE Now make OPT=-DROCKSDB_LITE shared_lib -j32 would work Test Plan: make clean make OPT=-DROCKSDB_LITE shared_lib -j32 make clean make OPT=-DROCKSDB_LITE static_lib -j32 Reviewers: sdong, igor Subscribers: dhruba, leveldb Differential Revision: https://reviews.facebook.net/D36825
