Bootchart complains about missing ld-linux.so.* during boot on PowerPC

Binary package hint: bootchart

Karmic Koala booting on PowerPC (iBook G4) always displays this message:

    cp: cannot stat `/lib/ld-linux.so.*': No such file or directory

After two months of seeing it everytime I power up my laptop I finally got down to investigating the cause. I found that bootchart's initramfs script does something like this:

    if [ "`uname -m`" = "x86_64" ]
    then
        mkdir $JAIL/lib64
        cp /lib64/ld-linux-x86-64.so.* $JAIL/lib64
    else
        cp /lib/ld-linux.so.* $JAIL/lib
    fi

Unfortunately on my PowerPC system there is no ld-linux.so.* but there's ld.so.1 instead:

    wojtekka@ibook:~$ ldd /bin/true | grep ld
            /lib/ld.so.1 (0x48000000)
    wojtekka@ibook:~$ ls -l /lib/ld*
    -rwxr-xr-x 1 root root 133856 2009-10-07 18:18 /lib/ld-2.10.1.so
    lrwxrwxrwx 1 root root 12 2009-10-20 23:06 /lib/ld.so.1 -> ld-2.10.1.so

I guess another platform-specific condition will be required. For the record, `uname -m` returns "ppc" here.
