On principle, I do agree with Thomas.

However, I would point out that this is way wider than just the script
image. Indeed, we also have HOST_UBOOT_TOOLS_GENERATE_ENV_IMAGE which
is only called at install time.

If we wanted to mandate clean, separate build and install steps for the
script image generation, so would we want for the environment image too.

Which is a wider endeavour than just catering for the script image.

Of course, if one would want to actually tackle the issue and actually
separate the build and install steps, that would be awesome.

Otherwise, I am fine with just the mkdir.

Yann E. MORIN.
