Cross Compiling MD needs important update.

[Alex Frick]

It is mentioned nowhere in https://chromium.googlesource.com/chromium/src/+/refs/heads/main/docs/win_cross.md that one must export DEPOT_TOOLS_WIN_TOOLCHAIN=0 in order for vs_toolchain.py update --force --no-download to work correctly. I had tried numerous times to cross build instead of having to boot into windows. And it was only after remembering I had set DEPOT_TOOLS_WIN_TOOLCHAIN=0 on my windows machine that I tried that and it worked. This needs to be added to the cross building md in the same section as https://chromium.googlesource.com/chromium/src/+/refs/heads/main/docs/win_cross.md#if-you_re-not-at-google because this would not be clear to someone who hasn't built on a windows machine, or even if they had, there is no indication that DEPOT_TOOLS_WIN_TOOLCHAIN=0 is needed outside of a native windows build.

It's working fine here. What kind of errors are you getting?

It seems like you're asking a different question, so it doesn't make sense to reuse this thread. It looks like this is related to your other thread on cross-compiling for Mac, though.
