I am trying to take advantage of the new release of c-lightning 0.6 that provide the ability to setup a lightweight node (i.e. No Local bitcoind instance running). But did not found any documentation how to do that yet.
What should I do in order to have a lightning node running a lightweight node? Is there a specific flag to use? or it is just a call from bitcoin-cli with a remote connexion flag setup on it?
Current setup:

One lightweight alternative that I use quite often when setting up a Lightning node is spruned. The following will get you up and running:
Install some dependencies:
apt-get install -y git python3 \
libleveldb-dev \
python3-dev \
git \
gcc \
g++ \
python3-pip
Get spruned and its dependencies:
git clone https://github.com/gdassori/spruned.git spruned
cd spruned
git checkout 43e197693278fd551b165c6cfa5de78f853ef554
pip install -r requirements.txt
The third line is currently needed since the master commit is currently broken.
Next you can start the lightweight node with the following:
python3 spruned.py --network bitcoin.mainnet --datadir data --debug --rpcuser=rpcuser --rpcpassword=rpcpassword
Once the node is running you can start c-lightning like this:
lightningd --log-level=debug --network=bitcoin \
--bitcoin-rpcuser=rpcuser \
--bitcoin-rpcpassword=rpcpassword

I'm the developer of the spruned Bitcoin client, thank you for posting that.
I always told that spruned is highly experimental. At the moment, however, I'm confident to advice the latest 0.0.5 release as stable enough to keep a c-lightning mainnet instance in sync.
The latest release on pypi includes an electrum based fee estimation quorum and a robust P2P connection pool with a 100% blocks hitrate.
Today, the bandwidth usage is still high and cannot be used on metered connections.
