[S390] zfcpdump: Prevent zcore from beeing built as a kernel module.
The zcore code switches to real addressing mode when creating a kernel dump. This is not possible, if it is built as a kernel module. With this patch zcore (zfcpdump) can't be built as a kernel module any more. Signed-off-by: Michael Holzheu <holzheu@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
