* guix/build/asdf-build-system.scm (copy-files-to-output): Don't attempt to
  reset timestamps on files without write access.
  (install): When parent SBCL package is in the inputs, use its source.  This
  way we get possibly patched sources in CL packages as well (e.g. for FFI).
  This is also useful for sources that generate files on load-op, like cl-unicode.

* guix/build-system/asdf.scm (package-with-build-system): Forward the SBCL
  parent as a native input so that it can be used in the install phase above.
