[oe] [meta-oe][PATCH] libdbi-perl: prevent native libdbi-perl depending on target perl

[Tim Orling]

Sorry for clobbering this change previously. I hadn’t seen the commit
message about the error and I meant to send an email to open up discussion
once I saw it (randomly)...we discussed it in the bug triage meeting and a
weekly engineering sync meeting.

I do wonder why this is needed (which is why I naively dropped it), or
better said why other Perl modules are not affected. This feels like a fix
for an underlying problem. I would expect ALL libfoo-perl recipes to have
the same behavior. Bitbake is supposed to be smart enough to handle
RDEPENDS properly for native recipes.

Have you only seen it on this package because of usage, or is it special in
some way? Did it affect releases before the perl-cross change when we moved
to perl 5.28.0? Trying to sleuth out the underlying cause...otherwise we
need a sweeping change for all other native perl module recipes...
