+Upstream-Status:Inappropriate [embedded specific]
+
+This removes all the logic that perl uses to locate an appropriate
+errno.h for the target. Instead we simple create a file that does
+
+  #include "errno.h"
+
+and use that as the file to parse. This is needed when using an
+external toolchain since perl will search in ${STAGING_INCDIR} for
+errno.h (when using gcc) and that isn't where it's located - its
+wherever the external toolchain keeps it's headers.
