You could install Gentoo into a directory without the build tools, but
you would have to install packages and update them from a full Gentoo
installation outside that directory. I've used that technique in my
Docker experiments.[1]

emerge --root=/workdir sys-apps/busybox will install busybox and all
build-time dependencies into /workdir.

Kind regards, tastytea
