configure:11349: error: Found linkable libevent in /tmp/tor-win32/prefix, but it does not seem to run, even with -R. Maybe specify another using --with-libevent-dir}

The problem seems to be runtime linking

find -name libevent-2-1-6.dll
./prefix/bin/libevent-2-1-6.dll
./src/libevent-2.1.8-stable/.libs/libevent-2-1-6.dll

I installed MSYS and Mingw on it and I compiled a static Tor for Windows successfully with this project: https://github.com/cretz/tor-static

The only problem is that you'll need to have access to a Windows host, I tried to install MSYS on Wine in Linux and the installer is buggy.
