This patch fixes the issue described below, which IIUC originates in a
mere typo in commit 671862f6b3089c3a503c1b6936a821ad54429359

1. emacs -Q
2. M-x apropos-library elisp-mode RET
3. The *Apropos* buffer incorrectly lists methods that elisp-mode.el
   defines as if they were _features_ provided by the library.
   Accordingly, clicking on one of those references yields an error such
   as "Unknown library `xref-backend-definitions'"
