New issue by am11 on void-packages repository

https://github.com/void-linux/void-packages/issues/14489

Description:
### System

* xuname:  
`Void 4.9.184-linuxkit x86_64-musl GenuineIntel uptodate rF`

* package:  
base-minimal

### Expected behavior
A base installation of Void Linux, in both glibc and musl-libc editions, has the tool called ldconfig, which helps applications and other tools to find out which system libraries are installed.

`ldconfig` does pretty much nothing on musl-libc based systems. The alternative is scanelf for musl-libc, which pax-utils package provides.

In minimal Alpine Linux installation, pax-utils is included. The expectation from Void Linux (musl-libc edition) is also to have pax-utils as part of minimal install (docker scenario).

### Actual behavior

There is no usable tools available in base-minimal for system-library introspection.

### Steps to reproduce the behavior

glibc case

```sh
docker run -it voidlinux/voidlinux dash # glibc edition

ldconfig -NvX
# lists the installed system libraries
```

musl-libc

```sh
docker run -it voidlinux/voidlinux-musl dash # glibc edition

ldconfig -NvX
# returns nothing
# it's pretty much a no-op on musl, alternative is 'scanelf'

scanelf
dash: 2: scanelf: not found

xbps-install -S
xbps-install pax-utils

scanelf --ldpath -BF '%f'
# lists the installed system libraries
```
