This is usually the kind of thing people have a repo for somewhere. :)

(It's long and complicated enough it might be nice if it were versioned...)

This is... dense.

This is probably the most immediately interesting line of it to me:

for i in BC DIFF EXPR GROUPADD GZIP ROUTE SH TR USERADD VI WGET

hmmmm....

  sed -i "s/<(.*)/:/" s*/*

The script you're running this on can't handle bash syntax? Except why are you
doing that _after_ running defconfig?

Why do you do:

  mv root/*/*/usr/src/distfiles/* ../pkgsrc/distfiles

_before_ running "make root"? And what context does:

  cd ../../../../*x-*

run in? (It looks like you're in the toybox source dir? From the start of the
script you cloned some repos off of github and cd'd into toybox, and now you're
cd-ing three levels above that?)

I haz a confused.

I'm still working my way through to the end of "make root in toybox". Have to
look at what you did _in_ that root in the morning...

My build systems have all run as a normal user (NOT requiring root on the host)
since about 2004. (Point of pride. :)

This is what "alias" is for. :)

It looks like the pieces are here, I just have to do some squinting. Thanks.
