Bug 1566225

Between Fedora-Rawhide-20170406.n.0 - https://kojipkgs.fedoraproject.org/compose/rawhide/Fedora-Rawhide-20180406.n.0/logs/ppc64/buildinstall-Everything.ppc64.log - and Fedora-Rawhide-20170407.n.0 - https://kojipkgs.fedoraproject.org/compose/rawhide/Fedora-Rawhide-20180407.n.0/logs/ppc64/buildinstall-Everything.ppc64.log - this error started making the buildInstall compose phase for ppc64 fail:

2018-04-07 08:18:48,354: command returned failure (127)

The obvious thing that changed between those two dates is the kernel went from 4.17.0-0.rc0.git1.1.fc29.ppc64 to 4.17.0-0.rc0.git4.1.fc29.ppc64.

What ppc.tmpl does there is this:

    ## kernel-wrapper magic that makes the netboot combined ppc{32,64}.img
    runcmd ${inroot}/${WRAPPER} -p of \
           -D ${inroot}/${WRAPPER_DATA} \
           -i ${outroot}/${KERNELDIR}/initrd.img \
              ${outroot}/${KERNELDIR}/vmlinuz \
           -o ${outroot}/${NETIMG}

(where $WRAPPER is 'usr/sbin/wrapper' and $inroot is the installroot, in this case var/tmp/lorax.3lrsa69u/installroot ).

What kernel-wrapper does is this:

# Calculate the vmlinux.strip size
${CROSS}objcopy $objflags "$kernel" "$vmz.$$"
strip_size=$(${CONFIG_SHELL} "${srctree}/scripts/file-size.sh" "$vmz.$$")

I am not sure where $srctree is supposed to come from or what it's supposed to be, but at present it appears to be nothing at all, which could be the cause of the problem. We also can't see what it was before this broke, as it's not printed anywhere when it works, AFAICS.
