Commit 62ec87680a61 ("common.mak: improve cross compilation support")
added one extra whitespace during the changes of the toolchain command
definitions. The rest of the commands did not receive that change.
Since then the pretty print output looks like this:
...
CC zipl/boot/eckd1b.o
CXX ziomon/ziorep_collapser.o
SED zdev/src/lszdev_usage.c
CC hyptop/sd_cpu_items.o
MV zfcpdump/zfcpdump-initrd
LINK dasdfmt/dasdfmt
...
Add the additional whitespace to all other tools definitions used during
the build process.
Note: This doesn't fix the misaligned indentation for commands like
$(CC_FOR_BUILD) as those inherit the whitespace from the original
command, here $(CC).

zfcpdump: S390 SCSI dump tool (Version 3) ========================================= zfcpdump is used for creating System dumps for Linux on System z. It has two parts: a zfcpdump enabled Linux kernel and a user space application. This is the 3rd version of zfcpdump which uses the upstream kernel version 3.12 or above. This version writes the dump to a partition in contrast to the previous versions where the dump was written to a file system. The user space application of zfcpdump can reside either in an intitramfs or an initrd. It reads from /proc/vmcore, provided by the kernel part, and writes the system dump to a SCSI disk partition. To build a zfcpdump enabled kernel use the following settings in your kernel configuration: * CONFIG_ZFCPDUMP=y * CONFIG_BLK_DEV_INITRD=y * CONFIG_EFI_PARTITION=y for using GPT disk layout * CONFIG_MSDOS_PARTITION=y for using MSDOS disk layout * BLK_DEV_SD=y * Enable ZFCP driver * Enable SCSI driver * Disable as many features as possible to keep the kernel small. E.g. network and file system support is not needed at all. You can use "make zfcpdump_defconfig" as a starting point for your kernel configuration. * Issue "make bzImage" to build the zfcpdump kernel image. In a Linux distribution the zfcpdump enabled kernel image must be copied to /lib/s390-tools/zfcpdump/zfcpdump-image, where the s390 zipl tool is looking for the dump kernel when preparing a SCSI dump disk. Create and install initrd ========================= * make Builds "cpioinit" and statically linked "zfcpdump" application. Then cpioinit is used to integrate the zfcpdump application into the cpio archive zfcpdump_part.rd. * make install The initrd zfcpdump_part.rd is installed to "/lib/s390-tools/zfcpdump/". Additional information ====================== For more information on how to use zfcpdump and zipl refer to the s390 'Using the Dump Tools' book, which is available from: http://www.ibm.com/developerworks/linux/linux390.
