installer_cross / meson: ruledit-installer
Something has broken. Likely some tool update on my host machine. Can't push this patch in its current form, as it's likely not to work on nightly builds machine either.
We likely need crosser-2.5 ( #45701 ) first.
Existing patches apply and work with crosser-2.5
Add ruledit-installer support for installer_cross / meson.
Apply low-level meson-winbuild.sh part also to S3_1.
