Undefined reference to std::__cxx11:: errors (Bash on Ubuntu on Windows) - c++

Question

Windows 10 Anniversary Update came out a couple of months ago, and I'm trying out the new "Bash on Ubuntu on Windows" feature.
I used it to compile some of my previous projects (finished on a normal Ubuntu machine), and while most of them were successfully built, a few of them received multiple undefined reference to ... (std::__cxx11::... errors when building the entire project (after compilations on separate files are done without errors).
I tried switching to g++-4.8, g++-4.9, g++-5.4 and g++-6.2 and all of them came down to the same result. I also tried adding compiler option -D_GLIBCXX_USE_CXX11_ABI=0/-D_GLIBCXX_USE_CXX11_ABI=1 in Makefile and still ended up with the same errors.
Here are parts of these error messages:

Since most of my projects did build successfully, I wonder if it's possible to solve the problem by toggling some settings without jumping to the conclusion that this is simply a result of "Bash on Ubuntu on Windows" still being a "beta" feature.
