Hard-coding a check in startup.el based on a setting for HOME that
happens to be used by the test-suite doesn't look like a good solution
to me. I'm not familiar with the native compilation branch, so I won't
try to suggest an alternative. Also, the Emacs tests generally try to
clean up when they exit, and it looks like nothing ever deletes this
temporary directory?
