interpreters/ficl: Fix compilation issue

A NuttX user told that ficl wasn't working as suggested in the
README.txt, then I found that the root cause was the order of the
Make.srcs inclusion inside the Makefile. I think we can do better:
we could automate the process to download and configure ficl.
