Now, Spacemacs loads as well with master.

Yes, Emacs master builds and works in console (same issue for packages manager, bug #25221) but I have to

echo 0 | sudo tee /proc/sys/kernel/randomize_va_space

before the build starts otherwise it fails.

Yes, this is needed and that won't change until unexec is removed from emacs (either replace by portable dumper or loading everything at runtime).
