[OE-core] [Openembedded-architecture] [WIP] perl upgrade to 5.26.2

[Alexander Kanavin]

For what it's worth, I have started a similar project, but in a more
radical way: rewrite existing recipe (unmaintainable mess imo), bring
in perl-cross overlay from buildroot to do cross-builds without
resorting to ugly hacks. I got a bit further: the whole thing builds
and packages without errors or warnings but failures happen later in
perl-dependent recipes. I hope to pick it up at some point later:
