What I encountered is: when installing MingW32, by default, it only install "gcc". So in the system, g++ is still the GNU version, so it cannot find MingW32 liblto_plugin-0.dll. I guess the g++ running in your environment is not the one you intend to use.

$ which gcc
/MinGW/bin/gcc

$ which g++
/usr/bin/g++

$ gcc --version
gcc.exe (MinGW.org GCC-8.2.0-5) 8.2.0
