[tex-live] Polyglossia breaks XeLaTeX

[Uwe Siart]

As the others already mentioned: pdflatex is called instead of xelatex.
I believe that either your editor is fooling or you are making a mistake
in using it.

This message is not from LaTeX output. It is created by your editor and
it makes you believe that you ran XeLaTeX. But ...

Clearly: pdflatex is actually called. So no surprise that ...

Try to figure out what your editor is doing behind the scenes. This
error is not related to polyglossia or xetex (or TeXLive even) at all.
