You failed to link the DLL properly - you need to provide a proper mingw32 CRT
startup object and specify an entry point. So, you should additionally link in
dllcrt{1,2}.o from mingw32 runtime and use _DllMainCRTStartup at 12 as an entry
point (just -e _DllMainCRTStartup at 12).

It's better not to use mingw32-ld directly if you don't know precisely what is
necessary to link in and how. Consider using -shared option of llvm-gcc. The
following cmdline does everything for you and yields a working .dll:
llvm-gcc -shared tdll.c -o tdll.dll
