bug#49507: 28.0.50; macOS: Symbol’s value as variable is void: lock-file-name-transforms

[Naofumi Yasufuku <naofumi@yasufuku.dev>]

Precondition:
- Repository revision: 9ce6541ac9710933beca7f9944087fe4849d5ae9
- macOS
- $ mv ~/.emacs.d/eln-cache ~/.emacs.d/eln-cache.old

Emacs doesn't start due to the following error:
  $ ./src/emacs -Q
  Symbol’s value as variable is void: lock-file-name-transforms
  $

I've not seen such error under linux.  At least, this issue disappears
if make_lock_file_name() in src/filelock.c is reverted.
