I try to bootstrap again under Ubuntu 18.04LTS, and encounter this problem again.
A temporary solution is to patch the m4-1.4.18 with this:

https://github.com/easybuilders/easybuild-easyconfigs/files/2737214/M4_glibc_2.28.patch.txt

(From https://github.com/easybuilders/easybuild-easyconfigs/issues/7383)

However, the problem doesn't appear in Arch.

I can't reproduce the bug anymore.  Could you confirm?

Yes.
 
And I also tried it at Ubuntu 20.04. The same problem occurred again.

stage1.log：

Can you reproduce it on Ubuntu 18.04 again?

> Can you reproduce it on Ubuntu 18.04 again?

Strangely, now I can't reproduce it on 18.04.
But I can still reproduce it on Ubuntu 20.04 and Arch.
I don't know why.
