I've got the server building all targets now. (x86 worked, arm didn't, not
sure why yet, could easily be something I screwed up at my end over the
weekend.)
I hope to get the nightly regression testing up and running in the next couple
days. That should help find these earlier. (And I owe you 1.17.0 binaries for
all targets. Do you still want 1.16.2 binaries, or just the most recent?)

*shrug* It can be turned off. My concern is it not breaking defconfig built on
other hosts or for other targets.
If I could actually use defconfig instead of my allnoconfig
KCONFIG_ALLCONFIG=trimconfig thing, that would be an improvement...

It's little things. For example, realpath has been available as "readlink -f"
for years. In toybox, I would have had realpath be a sub-option of readlink
that added an alias. In busybox, it's a second applet that shares no code
with the first.
(See attached toybox readlink.c and then a howto.patch for how I'd have added
realpath on top of it. The patch is untested, but took me about 4 minutes.)

*shrug* I disabled most but not all internationalization support in the
uClibc I'm building, so I dunno if it's got sufficient unicode stubs or not.
Let's see..
I switched it back on and it built, and booted to a shell prompt where I could
run "ls -l", so I'm calling it good. :)

You're right, I just confirmed this.

I don't have strong objections to unicode, of the 8 gazillion
internationalized character sets I've seen it's the _only_ sane one.
But the internationalization bits that force you to set an environment
variable to get "sort" to stop sudenly being case insensitive, those were a
bad idea.

I'll try swapping the trimconfig for updated defconfig later today and report on
the results. For now, lunch break over, back on my head...
