Building on a 32 bit toolchain on a 64 bit Windows fails

[tzaeru]

Running cargo build with the toolchain stable-i686-pc-windows-msvc results in "The application was unable to start correctly (0xc000007b)" when the build process tries to run build-script-build.exe. build-script-build.exe seems to link against 64bit libraries while being 32bit itself.

I might be missing something here about the Windows development environment, as I am gratendly not overtly familiar with it, but I've 32-bit versions of MSVC and VC++ redistributables installed.
