This is because ngetty was built using a version of dietlibc that uses
the deprecated "vsyscall" entry points to the kernel, and you are using
a kernel with vsyscall disabled.
This will be fixed by rebuilding ngetty. But the older version should
still work if you rebuild your kernel with
CONFIG_X86_VSYSCALL_EMULATION enabled (or, if it's already enabled,
change the vsyscall kernel parameter).
