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.

Module::ExtractUse is basically a Parse::RecDescent grammar to
parse Perl code. It tries very hard to find all modules (whether
pragmas, Core, or from CPAN) used by the parsed code.
"Usage" is defined by either calling use or require.
