[Libreoffice] maybe clean rebuild needed

[Markus Mohrhard]

Hey,

I just enabled the macro's test in calc again and it seems that in
some situations we get a deadlock in the first incremental build after
the patch. If you observe that in your build, do a make clean and the
next make should execute the test without a problem.

If you still get problem after a make clean please write me a mail.

Sorry for the trouble I might cause.

Markus
