This has nothing to do with AUCTeX but it seems that your emacs has a
wrong `shell-file-name'.  The docs state:

--8<---------------cut here---------------start------------->8---
shell-file-name is a variable defined in ‘C source code’.
Its value is "/usr/bin/fish"
Original value was "/bin/bash"

Documentation:
File name to load inferior shells from.
Initialized from the SHELL environment variable, or to a system-dependent
default if SHELL is unset.  See Info node ‘(elisp)Security Considerations’.
--8<---------------cut here---------------end--------------->8---

As far as I can see in Emacs's callproc.c, the default value for
`shell-file-name' is the value of the SHELL environment variable or
/bin/sh if SHELL is not set.  So I would conclude that either your SHELL
environment variable is already wrong or that `shell-file-name' is
explicitly set in your ~/.emacs (or somewhere else that gets loaded).
