+Upstream-Status:Inappropriate [native]
+
+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.
