This is a normal behavior and you can ignore the errors.

Why it happens?

1. Make runs "clean" before "all"
2. At this point no submodule is initialised.
3. So, when make run "make -C extern/filecoin-ffi clean" , there is no file inside "extern/filecoin-ffi"
4. This results in the error you see.

If you want to test this theory then run the following steps:

1. git clone https://github.com/filecoin-project/lotus.git
2. cd lotus/
3. git submodule update --init
4. make clean all

You should not see any errors as submodules have been downloaded and Makefile for filecoin-ffi exists on the system.

run "git submodule update --init"
----shows "GnuTLS recv error (-54): Error in the pull function.", reboot the system and try again, it works.

run "make clean all"
----it stuck in downloading "go: downloading github.com/ipfs/go-ipfs-blockstore v1.1.2", see log below:

This seems like a system command issue. You need to check this on your side. Nothing to do with lotus.

Stuck download could be a network issue or issue with golang version. This is again not specific to lotus.
