Proper handling of test references

[kilian]

The reference data for unit tests are currently copied into the build directory via their common directory. make distcleancheck doesn't like it because deleting them would violate file permissions. Find a workaround, so Jenkins can report success.

Actually, I saw an issue when running the extra-distcheck. Strange, we will see ...

[Juergen Reuter]

This breaks for some reason make extra-distcheck, namely for the option --disable-noweb-force --disbable-ocaml" with these error messges:

Investigating.

[Juergen Reuter]

Got the problem, it's on old trap from the dark side of automake.

[Juergen Reuter]

Done finally in #4040.
