mentions-deprecated-usr-lib-perl5-directory

As of Perl 5.20, the vendorarch directory is /usr/lib/<triplet>/perl5, but this package still uses usr/lib/perl5 in some of the files under debian/. Please replace that with the value of $Config{vendorarch} configuration parameter, e.g.

$(shell perl -MConfig -wE'say substr($$Config{vendorarch},1)')
Severity: error
Experimental: true
