workaround for huge musl binaries
...
something in our configuration is causing gcc to generate binaries
in excess of 68K for "hello world". hardeningDisable seems to stop it
doing that, turning it on for s6 which writes _lots_ of binaries
but would be good to get to the bottom of this

rewrite preinit as very small C program
...
By using the kernel "nolibc" header to avoid requiring a C library, we
can bring the initramfs size to around 4k
This does involve a tiny bit of inline mips assembly which I'm not
sure about. gcc seems unwilling to generate the code to load $gp at
function entry of main(), so we do it by hand - but I'd rather find
out why gcc doesn't.

support jffs2, with initramfs
...
the jffs2 filesystem contains only /nix/store and a script which is
run in early init (initramfs) and is responsible for recreating
"traditional" directories (/bin /etc/**/* /var &c) based on the
configuration.
this is tested only in qemu so far and could use some cleanup
