My OS: macOS Catalina 10.15

I git clone emacs HEAD source code from GitHub and `cd` in. 

My build steps:

1. ./autogen.sh
2. ./configure
3. make

And it stop at 

```
Loading /Users/ccQ/Downloads/emacs/lisp/loaddefs.el (source)...
Symbol’s value as variable is void: ctl-x-6-map
make[1]: *** [bootstrap-emacs.pdmp] Error 255
make: *** [src] Error 2
```

Do I miss something? These build steps work fine several days ago.
