different `temporary-file-directory' and I can not figure out how to
adjust API to handle such case. On the other hand I am unsure if it is
a realistic case when this function is called with

I have a case where the current way of forcing the temporary directory
to me `/tmp` is wrong. Running emacs on Ubuntu **under WSL2**,,
exporting latex snippets to ODT *as images* fails : the `.dvi` files
are correctly compiled and placed in `/tmp{, but the convert program
tries to read them in `../../../../tmp/`, which is indeed `/tmp` in a
"normal" filesystem but **is not** in WSL, where the root (`/`) is in
fact a mounted tree.
Admittedly, this is a corner case, but it turned out to be necessary
(exporting via mathml gave unsatisfying results).
