It turns out this problem is not my fault actually.  Here's how to
simulate it.  Download

  
https://alpha.gnu.org/gnu/emacs/pretest/windows/emacs-27/emacs-27.1-i686-no-deps.zip

(Why 27.1?  It seems to affect 27 upwards.)

Unpack it.  Run emacs -Q.

--8<---------------cut here---------------start------------->8---
C:\sys\emacs-27-no-deps\emacs-27.1-x86_64\bin>emacs -Q
--8<---------------cut here---------------end--------------->8---

No problem.

Now create a directory called lib-src at the source of your GNU emacs
installation, then run emacs -Q.  You'll get:

--8<---------------cut here---------------start------------->8---
C:\sys\emacs-27-no-deps\emacs-27.1-x86_64>mkdir lib-src

C:\sys\emacs-27-no-deps\emacs-27.1-x86_64>cd bin

C:\sys\emacs-27-no-deps\emacs-27.1-x86_64\bin>emacs -Q
Warning: Lisp directory 
'c:/msys64/home/Administrator/emacs-build/git/emacs-27.1/lisp': No such file or 
directory

C:\sys\emacs-27-no-deps\emacs-27.1-x86_64\bin>
--8<---------------cut here---------------end--------------->8---

There is something in the emacs source code that is sensitive to the
existence of the directory lib-src.
