[Toybox] Aboriginal Linux usage lists, FYI.

[Rob Landley]

I'm working to replace busybox with toybox in aboriginal linux.  I just
built all targets with TOYBOX=toybox and then did occurrence counts for
the commands.

The toybox commands:

    505450  toybox cat
     22852  toybox ln
     18392  toybox true
      5783  toybox dirname
      5561  toybox basename
      4414  toybox uname
      3090  toybox cmp
      2533  toybox sort
      2259  toybox cp
      1444  toybox rmdir
      1262  toybox sha1sum
      1092  toybox echo
       353  toybox sleep
       218  toybox which
       208  toybox xargs
        65  toybox env
        48  toybox id
        34  toybox patch
        32  toybox head
        16  toybox yes
        16  toybox wc

Remaining busybox commands used by the same build:

    519779 busybox sed
    378969 busybox rm
    116894 busybox grep
     55163 busybox expr
     36518 busybox mv
     18973 busybox mkdir
      9741 busybox egrep
      7519 busybox install
      6266 busybox chmod
      3539 busybox touch
      3188 busybox hostname
      2698 busybox ls
      2033 busybox tr
      2025 busybox diff
      1668 busybox awk
      1009 busybox mktemp
       978 busybox uniq
       953 busybox cut
       444 busybox find
       328 busybox tar
       316 busybox date
       160 busybox bzip2
       118 busybox tail
        64 busybox od
        48 busybox chown
        32 busybox whoami
        32 busybox dd
        29 busybox gzip
         8 busybox readlink
         7 busybox sh

Several of the command in the second list are partially implemented.
Among other things, I hope to fix them up so the provide what aboriginal
needs this weekend...
