Thanks Mario.

I've been making 64bit MinGW builds of x265 since the beginning without any
toolchain scripts like that.  You just need a 64bit MSYS and a 64bit MinGW
compiler and use the current build/msys folder as-is.

You only need to use a toolchain file when you are cross-compiling from
32bit MSYS to 64bit MSYS.

Is there a way to robustly query whether your MSYS is 32 or 64bit? It would
be good to handle this cleanly in the batch file.
