yes, its possible to have multilib capability for the mingw-w64
toolchain, but only with gcc trunk 4.5.0.

There are also more issues with multilib capable toolchains, gcc target
libs clashing. For example, make install currently tries to install
both 32bit and 64bit libstdc++-6.dll into the bindir.

Its a known issue, but it has yet to be fixed.
