3595e36294 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

fe99abc450 shrink rsync 
remove openssl requirement, it  uses it for "optimised assembly
versions" of md5 - but only on x86/arm/sparc not mips anyway

98243d43da add mtdutils mkfs.jffs2 --graft option 
we'd like a bit more of the convenience of mksquashfs
(never thought I'd say _that_) for jffs2, in particular
not having to copy all the desired store paths into a
single directory just so we can create an image from them

a172180be8 don't set lua5_3 in overlay 
sphinx depends on lua5_3, so overriding it globally means rebuilding
that - which isn't really necessary

4b19568f1b add kexecboot 
This allows booting a new image from a running OS, creating a
phram mtd for the root squashfs

* enable CONFIG_KEXEC
* add modules/kexecboot
* patch kexec-tools to add --map-file option for the squashfs
* patch kernel kexec code to call new kernel with DTB

08bed15cf8 ssh service 
- dropbear
- generate host keys on first use
- mount /dev/pts

It's not ideal having the host key disappear when the device is
reboot, but without persistent storage the alternative is generating
it at build time. Deferring this problem to another time

run e.g. "waitup wlan0 10" to wait until wlan0 is operationally
