>Description:
math/maxima fails to start with SBCL when quicklisp is installed and enabled.

Because the maxima port is usually compiled as root but runs as a regular user, when it invokes SBCL with quicklisp enabled, it tries to access non-existent /root/.cache/common-lisp directory instead of $HOME/.cache/common-lisp of the invoking user. This causes SBCL to go into debugger-mode.

>How-To-Repeat:
Just install quicklisp for SBCL, i.e. add this to your ~/.sbclrc via quicklisp's setup function:

;;; The following lines added by ql:add-to-init-file:
#-quicklisp
(let ((quicklisp-init (merge-pathnames "quicklisp/setup.lisp"
                                       (user-homedir-pathname))))
  (when (probe-file quicklisp-init)
    (load quicklisp-init)))

Then, make and install math/maxima port with SBCL as default lisp, and run as regular user.
>Fix:
As explained in the following bug report of a Linux distribution:
  https://bugs.archlinux.org/task/29882
we need to disable user-specific initializations, i.e. prevent ~/.sbclrc
from running when maxima is invoked.

To do this, apply the attached patch to the startup script.
