perl-XML-XPath-1.34-1.fc25 fails to build in F25 if weak dependencies are disabled:

This is because ExtUtils::MakeMaker generates MYMETA files only if CPAN::Meta is installed. And because it's optional, CPAN::Meta is only recommended by perl-ExtUtils-MakeMaker.

Solution is either build-require perl(CPAN::Meta) by perl-XML-XPath or change t/meta-json.t and t/meta-yml.t tests to check for existence of the files and skipt the tests otherwise.
