An additional complication is that file-equal-p is intended to compare existing files ("If FILE1 or FILE2 does not exist, the return value is unspecified."), but the xref-elisp-location values do not seem to be so constrained. In elisp-mode-tests.el there are examples like
(xref-make "(defun xref-find-definitions)"
(xref-make-elisp-location
'xref-find-definitions nil
(expand-file-name "../../lisp/progmodes/xref.el" emacs-test-dir)))))
but also
(xref-make "(defun buffer-live-p)"
(xref-make-elisp-location 'buffer-live-p nil "src/buffer.c"))))
