[Libreoffice] oox/source/drawingml/customshapepresets.cxx is just too much for gcc

[Norbert Thiebaud]

I reverted

c9f9b6723b40279716b1e34c1441a33e60cceb58.
e36f591dfeb89fded172f4770157bc6cb6dc7454.

because  oox/source/drawingml/customshapepresets.cxx, a 4MB source,
made gcc blow-up both on Mac and on Gentoo....

The compiler churned on it for 20 minutes or consumming huge amount of
memory ( as in GBs)... and finally blow-up with memory error.
