Buildroot: how to add libraries

I am working on a buildroot project to make a small custom os. I only include the absolute necessary packages. One of the things I add is a precompiled program that uses certain libraries that are not included on the system. I want the system to include them, but I cannot find them in the buildroot menuconfig, linux-menuconfig or busybox-menuconfig.

menuconfig

linux-menuconfig

busybox-menuconfig

So my question is:
how do I add libraries to my system in buildroot?

I have tried searching for them in the menuconfigs and I have also tried to find information about this in the buildroot manual.

The libraries I want to include are:

ld-linux-armhf.so.3
libdl.so.2
libc.so.6


After some searching I have found that:

ld-linux-armhf.so.3

ld-2.*.*.so

libc

libc.so.2

The libraries you list are part of the C library, itself part of the toolchain. Buildroot will always provide those libraries, either by building a toolchain itself (what we call the internal toolchain backend) or by using an existing toolchain (what we call the external toolchain backend).
