In Fedora, we use this to build at least SOME debugging information (-g1
level rather than the default -g which exhausts the address space) for
QtWebEngine on 32-bit architectures:

(Also note that we build with
CONFIG+="webcore_debug v8base_debug force_debug_info"
or we would not be getting complete debugging information anywhere.)

The -g1 trick is probably also workable for QtWebKit if it is hitting the
same issue on any GCC target (including MinGW). But I don't know whether
Visual C++ has anything comparable.
