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.
