New chroot script whonix_shared/usr/local/share/whonix/chroot-scripts/70_install_486_kernel:
Only trying to install linux-image-486 kernel for compatibility (documented in FAQ) when build architecture is i686,
because trying to install linux-image-486 on x86_64 would fail.;

Whonix-Gateway_packages, Whonix-Workstation_packages:
Removed linux-image-486 (now done in whonix_shared/usr/local/share/whonix/chroot-scripts/70_install_486_kernel)
