make delete-old files always coming back

[Dennis Glatting]

Whenever I do an update these files keep getting reinstalled.

Taz# mk delete-old
>>> Removing old files (only deletes safe to delete libs)
remove /usr/include/nfs/krpc.h? y
remove /usr/include/nfs/nfsdiskless.h? y
>>> Old files removed
>>> Removing old directories
>>> Old directories removed
To remove old libraries run 'make delete-old-libs'.
