[REVIEW 3-5] Adapt SDK to changed paths in LO installation

[Stephan Bergmann]

Please review and cherry-pick to libreoffice-3-5 the commit 
<http://cgit.freedesktop.org/libreoffice/core/commit/?id=bcdadc2e9f3f6a400438cbbefffc60bf02baa0f1> 
"Resolves rhbz#789622: Adapt SDK to changed paths in LO installation".

Without it, SDK fails to build even simple examples, cf. 
<https://bugzilla.redhat.com/show_bug.cgi?id=789622#c2> "Trying to build 
libreoffice-voikko results in an error: 'cppumaker : init registries 
failed, check your registry files.'"
