[Issue 4014] CodeView debug type info not linked in from library

This is caused the implicite "-multiobj" flag being set when compiling into a
library. The debug type info is then in the module that contains the
init-struct for the class/struct. If never referenced (e.g. if initialization
is inlined), it will not show up in the executable.

A workaround is to not use -multiobj for libraries if they are compiled with
debug info, but this can add some link dependencies.
