* user-config/emacs/.emacs.d/init.el: Prior to moving emacs configuration to the guix store,
this issue didn't occur; however, after doing so, ~/.emacs.d/config.el is a symlink to a
store file. Because org-babel-load-file resolved symlinks before comparing their timestamps,
and config.org is now a symlink to a store file with an unchanging timestamp, config.org
changes never get tangled. To resolve this, instead we compare the symlink age of config.org
to the tangled file.
