32bit build cannot be compiled with debug info.

In !559 (closed) I was trying to provide Robert with some debug info from asan build. But I couldn't get yade to build with debug info, libyade.so was larger than 4GB (a max size limit on 32bit architecture).

Maybe for example we should build several .so files, like libyade-pkg.so , libyade-core.so and so on for each top directory?

Or maybe add an option to add debug info to only few selected files which need to be debuugged?
