I don’t know anything about nix, but I suspect it’s running make check
from a different location than it built emacs from.

Basically this test just checks whether a file exists and it uses the
built‐in variable source-directory, which must be set at compile time,
as the root. Presumably nix builds in a temporary location which it
removes before running make check.

If that’s true I can think of two ways round it:

  1. Create a temporary file and then check for its existence (e.g. in
     /tmp).
  2. Skip the test if the source directory doesn’t exist.
