If there is no System.map file for "make modules_install", scripts/depmod.sh will silently exit with success, having done nothing. Since this is an unexpected situation, change it to report a Warning for the missing file. The behavior is not changed except for the Warning message. The (previous) silent success and new Warning can be reproduced by: $ make mrproper; make defconfig $ make modules; make modules_install and since System.map is produced by "make vmlinux", the steps above omit producing the System.map file.
