Otherwise we can have `tst_` tag for all libraries inside LTP, but
divide them into categories according to their meaning:

- tst_*: test library
- tst_lib_*: libraries inside LTP
- tst_old_*: old test libraries

This will clearly state what are the LTP libraries, but separate them
according to their purpose.
