Add a test case for lp#1362875 (tested to break on 3.1.2).

(progn

  #+ecl (trace c::builder)

  (require 'sockets) ;; Test the pre-compiled system feature

  ;; Test that we didn't break require for non-asdf modules

  (progn

    (pop #+ecl ext:*module-provider-functions* #+mkcl mkext:*module-provider-functions*)

    (require 'serve-event))

  (operate 'dll-op :test-asdf/dll-test)

  (let ((dll (first (output-files 'dll-op :test-asdf/dll-test))))

    (si:load-foreign-module dll)
