This is what I was worried about.

As Documentation/process/changes.rst was modified in that commit,
it specifically requires GNU AWK.

Anyway, you were able to fix the build error
by installing /usr/bin/gawk.

If a distro installs gawk somewhere else,
(/usr/local/bin/gawk, for example), it is a problem.
The shebang "#!/usr/bin/gawk -f" will not work.
"#!/usr/bin/env gawk -f" will not work either.

More people may start complaining about it.
