With latest qemu several places where qemu-usermode is used e.g. nodejs, qtwebengine, chromium, the builds are failing form armv8a tuned machines (e.g. tegra) which is due to qemu crash ( SIGILL ) encoutered when 'max' ISA is used ( which is default ), max seems to use neoverse-n2 equivalent features, which is evident that SIGILL also happens when using -cpu neoverse-v2, therefore explicitly select neoverse-v1 for ISA, which works and covers almost all (if not all) cpu tunes for armv8 we have.
