The old org-latex-to-pdf-process variable (which you are initializing
in your latex.el file) has been renamed to org-latex-pdf-process. I
presume that you are not touching the latter, so it's left at default,
so the exporter ends up invoking pdflatex instead of xelatex.

You probably want to duplicate the setting in latex.el so that it will
continue working in both 8.0 and 7.9.4, rather than eliminating the old
one:

--8<---------------cut here---------------start------------->8---
(setq org-latex-to-pdf-process
  '("xelatex -interaction nonstopmode %f"
     "xelatex -interaction nonstopmode %f")) ;; for multiple passes

(setq org-latex-pdf-process
  '("xelatex -interaction nonstopmode %f"
     "xelatex -interaction nonstopmode %f")) ;; for multiple passes
--8<---------------cut here---------------end--------------->8---

or just:

--8<---------------cut here---------------start------------->8---
(setq org-latex-pdf-process org-latex-to-pdf-process)
--8<---------------cut here---------------end--------------->8---

(Untested).
