This patch is used for perl-native only. It enables the switching of
configuration files between Config_heavy.pl and
Config_heavy-target.pl by setting the environment variables
PERLCONFIGTARGET - the later containing settings for the target while
the former contains those for the host. This will allow cpan.bbclass
to use the settings appropriate for the native and/or target builds
as required. This also disables the use of the cache since the cached
values would be valid for the host only.
