perl: add a version that builds the recipe using perl-cross, and update to 5.28.1

perl-cross is a build system overlay from buildroot project that aims to bring
a bit of sanity to cross-building perl. The advantage of using that is that we
can drop a lot of custom patches (that no one really understands), and simplify
the perl recipe as well. Also the build time goes down from several minutes to
about 30 seconds. The whole thing becomes maintainable again, in my opinion.

When rewriting the recipe I had two goals in mind:
1. Stay with upstream defaults as much as possible
2. Add custom patches only when their necessity was proven through testing.
