[Libreoffice] debug compile failed on automation module

Hello,

After having recreate my local repository.
i've got a pb in automation and the rm -rf followed by build doesn't 
work (master branch on Debian x86 32 bits)
Here is what I get :
Making:    testtool
../unxlngi6/obj/testbasi.o: In function `SbxBase::SetFlag(unsigned short)':

With Matus and Norbert, we discussed about it on IRC. To sum up the 
discussion :
- basic has been moved to gbuild and seems that there are missing symbols
- in basicdllapi there are defines for BASIC_DLLPUBLIC, which is used fo 
exported symbols
- DbgName_SbxBase is made up by the macro DBG_CHKTHIS 
libs-core/basic/inc/basic/sbxcore.hxx
- debug code create exported symbol
- perhaps we could remove those DBG_CHKTHIS( SbxBase, 0 ); but maybe 
it's actually useful for something

If someone has an idea...

Julien.
