On systems with a POSIX shell:

--8<---------------cut here---------------start------------->8---
(let ((default-directory "/"))
  (read (shell-command-to-string "getconf LINE_MAX")))
--8<---------------cut here---------------end--------------->8---

Note, that this can differ when you connect to remote hosts. That's why
I have bound default-directory to a local file name in the example.
