Use Mozilla Porter stemmer for sqlite3, for CKJ FTS using FTS3 module in sqlite3.
Since sqlite 3.12.0, fts3 tokenizer requires SQLITE_ENABLE_FTS3_TOKENIZER
compiler flag.
Include this flag when you install sqlite:
export CFLAGS="-DSQLITE_ENABLE_FTS3_TOKENIZER" npm install sqlite3 --build-from-source
