When building U-Boot host tools for Windows from Microsoft Azure Pipelines, the following errors were seen:

It turns out tools/version.h is a symbolic link and with Windows default settings it is unsupported hence the actual content of tools/version.h is not what file include/version.h has, but the the linked file path, which breaks the build.
To fix this, remove the symbolic links for tools/version.h. Instead we perform a copy from include/version.h during the build.
