Subject: [PATCH] Fix linking of tests on MinGW-w64 GCC 5.1.

It worked flawlessly when crosscompiled from Linux, but compiling that
natively causes the linker to loudly complain about undefined references
to ConfigurationValue structs. I think it worked well under 4.9.2 (but
that mess had a slew of other ugly problems, such as complete inability
to produce non-crashing C++11 code under x64). The linker error is
caused only because I tried to reduce binary bloat, so I'm just
disabling that for MinGW and screw that. No problem under MSVC.
