FWIW - it looks to me like the grep call in cracklib-format is
concluding that cracklib-words is a binary file:

    buildroot/output/host/usr/sbin/cracklib-format cracklib-words-2.9.6.gz

    ]
    ]]
    binaryfilestandardinputmatches

If the grep is patched to have a -a to force the file to be treated as
text, then you get big numbers:

    skipping line: 1
    warning: input out of order: 'ghabcdefghabcdefghabcdefghabcd'
should not follow 'habcdefghabcdefghabcdefghabcde' (line 55362)
    warning: input out of order: 'fghabcdefghabcdefghabcdefghabc'
should not follow 'ghabcdefghabcdefghabcdefghabcd' (line 55363)
    warning: input out of order: 'efghabcdefghabcdefghabcdefghab'
should not follow 'fghabcdefghabcdefghabcdefghabc' (line 55364)
    warning: input out of order: 'fghabcdefghabcdefghabcdefghabc'
should not follow 'ghabcdefghabcdefghabcdefghabcd' (line 55366)
    warning: input out of order: 'abcdefghi' should not follow
'fghabcdefghabcdefghabcdefghabc' (line 55367)
    1911513 1911512

Or, if you use an older cracklib-words, like
http://downloads.sourceforge.net/cracklib/cracklib-words-20080507.gz,
then this problem is also avoided.
