Thank you, Lars and everyone.
Sorry for my absence.  I confirmed that 'LANG=ja_JP.UTF-8 emacs' starts
up without error after commit 561ef16fd0.

I agree that defcustom `custom-initialize-delay' implementation issue
still remains, and this workaround lacks a bit of consistency of
`make-lock-file-name' with custom `lock-file-name-transforms' variable.

In closing, let me summarize this issue:

--------
$ ./configure --with-native-compilation ...
$ make -j8 bootstrap


STEP 0)
Make sure that ~/.emacs/eln-cache doesn't exist.
Remove or rename it if exists.

$ mv ~/.emacs/eln-cache ~/.emacs/eln-cache.old


STEP 1)
Run emacs with $LANG that can invoke async native compilation
of lisp/language/*-util.el.

$ LANG=ja_JP.UTF-8 ./src/emacs -Q
Symbol’s value as variable is void: lock-file-name-transforms
$
$ LANG=zh_CN.UTF-8 ./src/emacs -Q
Symbol's value as variable is void: lock-file-name-transforms

$


TRACE)
This error can happen if `write-region' by async native compilation runs
at early stage of emacs startup.  Not macOS-specific.
