Build Fabric with FPC support

Run the following command:

cd $FPC_PATH/fabric
make

Common errors

Patching Fabric ...
Aborting! Tag on current HEAD () does not match expected tag/v2.3.0!

Seems that your Fabric is on the wrong branch. Try to run pushd $FABRIC_PATH; git checkout tags/v2.3.0; popd; followed by make again.
