But there isn't. After seraching the whole file system, these are all 
the files with remotely similar names:

----------------------
/usr/share/texmf/tex/context/base$ ls s-l*.mkiv
s-languages-counters.mkiv
s-languages-frequencies.mkiv
s-languages-hyphenation.mkiv
s-languages-sorting.mkiv
s-languages-system.mkiv
s-languages-words.mkiv
---------------------

I have the debian/ubuntu texlive distro that comes with ubuntu 15.10. 
ConTeXt says:

---------------------ConTeXt ver: 2015.05.18 12:26 MKIV current fmt: 
2016.3.18 int: english/english
