Solution 1: you don't!
Solution 2: you make sure that your call to the CL function can be replaced
by non-CL functions, using CL's compiler-macros.
(a compiler-macro is basically a compiler directive that tells how to
optimize/compile particular calls to a function. E.g. you can add
a compiler-macro to the function * such that (* 1 x) is replaced by just x.
IIRC the CL `list*' function has a compiler-macro that replaces most
calls to it by a combination of `cons' calls).
