David explained why AUCTeX compiles with "\input file.tex" here:
https://lists.gnu.org/archive/html/auctex-devel/2008-05/msg00055.html

Last year I tried to work on implementing a local variable to specify
the output directory, and so indirectly fix Alistair's problem, but
I've never finished it.  (One of) The main problem was how to share
such variable across multiple files of the same document (store it in
the auto file?), but there is the same problem for other variables
like `TeX-engine'.
