[PATCH?] docbook: make cleandocs

[Randy Dunlap <randy.dunlap@oracle.com>]

Hi Sam,

"make clean" cleans DocBook generated files, but I would like a way to
clean _only_ those generated files.  Something like the patch below,
except that it doesn't work.  :(

Can you give me ideas of how to fix it, please?

Thanks,

Add a 'make cleandocs' target to clean up all generated
DocBook files.
