The very first line of the AUCTeX output buffer from the LaTeX command
(C-c C-l) shows what actual command is used to compile your document.
If that command works in a shell but not from within auctex, I'm out of
ideas.

Quite unlikely, but maybe you configured AUCTeX's LaTeX command to
include the option -no-parse-first-line?  The parse_first_line option
has to be set to t in order to let pdflatex parse those %& magic lines.

AUCTeX just calls pdflatex for you if `TeX-PDF-mode' is on, so it
shouldn't have to be configured in a special way.
