Maybe add these earlier/higher?  Where the other write_make_var settings 
are?

Also, should these options be documented?  Like in the file's help()?

(Come to think of it, how about --with-libctf and --with-libfuse3? 
Should they also appear in --help?)

I think it makes more sense to have them at the end because they are not
really common options that people would use.  They are being added because
the GNU Coding Standards require them (and having them means that distro
build systems that expect a standard configure script can pass typical
options without complaints).

I'll add them to the help.

Should be done in a separate patch.

Actually, this is already part of the help output, by virtue of the 
help-overrides make target.
