Give a warning when system boost and stdlib-debug are used together

Browse Source 
In general this would lead to an immediate runtime crash because the
runtime checks of libstdc++ change the layout of some STL objects.
Therefore, this will only work when the boost libraries have been
compiled with this same flag. At this time, it is not known whether
any linux distribution contains such libraries.

Fixes bug #9736.
