feasible configuration is to place statically linked dependencies into
`./binaries`:
-+ [s6-portable-utils](https://skaret.org/software/s6-portable-utils/)
-`s6-applyuidgid`, `s6-echo`
++ [s6](https://skaret.org/software/s6-portable-utils/):
+`s6-applyuidgid`
++ [s6-portable-utils](https://skaret.org/software/s6-portable-utils/):
+`s6-echo`
+ [9base](https://tools.suckless.org/9base/):
`tr(1)`, `read(1)`, `urlencode(1)`
- there has not been a release in a long time. urlencode was added in
[51cdf1141edd627428ecf0b8bd643142dd5c3773](https://git.suckless.org/9base/commit/51cdf1141edd627428ecf0b8bd643142dd5c3773.html)
- and there has not been a tagged release since.
- some 9base commands do not build on my system, but thankfully none of the
tools required by httpd.execline fail.
