What are the values of those environment variables?

The way to run Hunspell with more than one dictionary is hinted upon
in the doc string of the command ispell-hunspell-add-multi-dic.  After
you invoke that command and specify the dictionaries you want to use
(e.g., in your case "en_GB,cs_CZ"), type this:

  M-x ispell-change-dictionary RET en_GB,cs_CZ RET

Then try spell-checking.  It should work with that arrangement.  It is
possible that you will first need to modify your environment variables
to prevent Hunspell from loading more than one dictionary by default.
