Is it even possible that these flags are not supported? I'd just add them unconditionally to LDFLAGS for mingw.

Yes, such toolchain builds exist. However, I asked mingw-w64 guys about them and it seems like can ignore those (these are some packages with patched gcc, not really supported by mingw(-w64)).

The attached patch adds those arguments unconditionally.
