I'm trying to use eglot over tramp using `emacs -Q -f package-initialize
-L /path/to/my/eglot -l eglot.el`. From what I understand, to
capture the remote process stderr, tramp creates a fifo, in
`tramp-sh-handle-make-process`, `tramp-sh.el:2889`. The MacOS mknod
command does not support the "p" parameter, so the communication with
the process does not work. Also no error is reported while the mknod
command is failing. I tried replacing `mknod %s p` with `mkfifo %s` or using gnu coreutils mknod. This
fixes the fifo creation but the process communication is still
broken after that.

I can reproduce the problem with

(let ((default-directory "/ssh:macos-laptop:"))
  (make-process
   :name "TEST"
   :buffer "*TEST*"
   :command '("sh" "-c" "while sleep 1; do echo $(hostname) out; echo $(hostname) err >&2; done")
   :connection-type 'pipe
   :coding 'utf-8-emacs-unix
   :noquery t
   :stderr (get-buffer-create "*TEST stderr*")
   :file-handler t))

And it works correctly with

(let ((default-directory "/ssh:localhost:"))
  (make-process
   :name "TEST"
   :buffer "*TEST*"
   :command '("sh" "-c" "while sleep 1; do echo $(hostname) out; echo $(hostname) err >&2; done")
   :connection-type 'pipe
   :coding 'utf-8-emacs-unix
   :noquery t
   :stderr (get-buffer-create "*TEST stderr*")
   :file-handler t))
