Hi Michael,

the issue is that here is not really the test function that is creating
this folder, but Emacs it-self that to operate needs a folder to store
and retrieve eln files.

For the test-suite we moved to a different folder than the one we use
for normal runs to have a clean environment to run the test-suite on.

Regards
