A quick side-by-side comparison of two directories shows that the following files are missing from the x64_x86 cross compiler folder but are present in the x64_x64 folder:
I then set up a cross compilation build environment using vcvarsall and the first two entries of my path are (in order):
C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Tools\MSVC\14.10.25017\bin\HostX64\x86
C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Tools\MSVC\14.10.25017\bin\HostX64\x64
So it looks like this matches up with what he's saying.
