The build depends on perl-native to retrieve the configuration
settings needed for the binding. cpan-base adds some useful functions
like is_target() and get_perl_version() that we need for
PERLCONFIGTARGET and related settings, which allow us to use the
target's Config_heavy.pl settings for ExtUtils:Embed when building for
the target.
Also adds the perl-modules dependency to give the target the perl
modules that scripts using the binding need.
