I can't reproduce this.  A small .tex file like this:

--8<---------------cut here---------------start------------->8---
\documentclass{article}
\usepackage{fontspec}
\begin{document}
foo
\end{document}

%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% TeX-engine: xetex
%%% End:
--8<---------------cut here---------------end--------------->8---

compiles with no problems for me, either by hitting `C-c C-c RET' or
from the menu Command->LaTeX.  Eval'ing

    (TeX-command-expand "xelatex -interaction=nonstopmode %s")

returns for me

    "xelatex -interaction=nonstopmode xelatex-test"

Standard debugging procedure I think: Start Emacs with -Q, eval
(package-initialize) in scratch buffer and then load your .tex file.  At
the end, a recipe to reproduce this issue is needed.

I've reassigned this report to AUCTeX.  Please open a new bug report for
the Gnus issue.
