I use menuconfig, defconfig, and allnoconfig.  The rest is there because
the kconfig infrastructure provides them.  Can't really say I've tested
them a lot.  Define "broken".

Actually it builds an include file out of toys/*.c and then that include
file is used to generate .config.

I note that when you add/remove a toys/*.c file you need to re-run "make
defconfig".  The .config<-generated/Config.in<-toys/*.c dependencies
don't quite go all the way through...

It's not created because it's not used.

Vestigial Kconfig stuff from Linux, via busybox.

To be honest, I'd like to replace kconfig entirely with infrastructure
that A) doesn't use ncurses, B) isn't GPL.  (It's a build tool that
doesn't ship in the resulting binary, but I'd like to clean it out anyway.)

The toybox build does not use this file.

And allnoconfig/allyesconfig.

If you'd like to submit patches to remove the non-working options, sure.
