[Libreoffice] recent push requires ~fresh rebuild

"Undo basis/brand split: move program/classes/ from basis to brand." 
requires manual tweaking in a rebuild, as it changes content of 
generated .component files based on changes in the central makefiles.

Short of make clean, what worked for me was, inside .../core,

find */unxlngx6 -name '*.component' -exec rm {} \;

(with "unxlngx6" replaced by your platform ID).
