Log message:
Bump the PKGREVISION for all packages which depend directly on perl,
to trigger/signal a rebuild for the transition 5.10.1 -> 5.12.1.

The list of packages is computed by finding all packages which end
up having either of PERL5_USE_PACKLIST, BUILDLINK_API_DEPENDS.perl,
or PERL5_PACKLIST defined in their make setup (tested via
"make show-vars VARNAMES=..."), minus the packages updated after
the perl package update.

sno@ was right after all, obache@ kindly asked and he@ led the
way. Thanks!

Log message:
Importing package for p5 module Class::OOorNO 0.011 as dependency of
scheduled import of p5 module File::Util.

Class::OOorNO helps a module handle the input for its subroutines whether
called in object-oriented style (as object methods or class methods with
the arrow syntax ->), or in functional programming style (as subroutines
imported to the caller's namespace via Exporter).
