Re: ABOUT-NLS not found when compiling from git master

[Nils Andre]

Because ABOUT-NLS just contains text, I used `touch ABOUT-NLS` to have
it be present.

Now, when I run `./configure --with-ssl=openssl`, I get another error
(again on both macOS (M1 Big Sur) and Linux (NixOS)):

```

```

Also on the note of ABOUT-NLS, it was removed in commit
be84711ea4509fefdc21a4b9bc69d421103871ad which mentions "it will be
autogenerated".

Thanks,

Nils
