[ISSUE] nfs-utils on void: ldd failure on installed .so

New issue by Vaelatern on void-packages repository

https://github.com/void-linux/void-packages/issues/53785

Description:
### Is this a new report?

Yes

### System Info

Void 6.6.67_1 x86_64-musl GenuineIntel notuptodate rrrnDDFFFFFFFFFFFF

### Package(s) Affected

nfs-utils libnfsidmap

### Does a report exist for this bug with the project's home (upstream) and/or another distro?

_No response_

### Expected behaviour

On glibc:

```
$ ldd /usr/lib/libnfsidmap/regex.so
        linux-vdso.so.1 (0x00007ffc5abab000)
        libc.so.6 => /usr/lib/libc.so.6 (0x00007fdadaa22000)
        /usr/lib64/ld-linux-x86-64.so.2 (0x00007fdadac3b000)
```

### Actual behaviour

On muslc:

```
$ ldd /usr/lib/libnfsidmap/regex.so
	ldd (0x7f0f5f58f000)
	libc.so => ldd (0x7f0f5f58f000)
Error relocating /usr/lib/libnfsidmap/regex.so: nfsidmap_config_get: symbol not found
Error relocating /usr/lib/libnfsidmap/regex.so: nfs4_get_default_domain: symbol not found
Error relocating /usr/lib/libnfsidmap/regex.so: idmap_verbosity: symbol not found
Error relocating /usr/lib/libnfsidmap/regex.so: idmap_log_func: symbol not found
```

### Steps to reproduce

This breaks my void-mklive workflows making dracut images of x86_64-musl with the nfs library installed. I remove the nfs library and it works again, so I've narrowed down my build problems to this library.

It seems consistently broken on musl, fixed on glibc. I've checked and it seems the libs are in fact compiled fresh on each build. Upgrading to 2.8.2 didn't help #53784 

I've not yet looked at how it's actually being built to see what is broken there.

Hi!

I can reproduce ACTUAL BEHAVIOR on a musl-based Void live system both for nfs-utils 2.7.1 and nfs-utils 2.8.2. Just for the record, there seems to be a [similar report](https://bugs.gentoo.org/734022) for Gentoo describing similar underlinking on musl.

And this problem is also present on Alpine. @ncopa

Skimmed the build itself, it's heavily indirected Make.

this also happens with `nsswitch.so`, `static.so`, and `umich_ldap.so` in the same dir

ok, this isn't underlinking but dracut trying to find dependencies for something that should only be loaded as a plugin, not as a standalone library. reported to upstream: https://github.com/dracut-ng/dracut-ng/issues/1087

Attempting a test on the rig where I detected the problem for starters. It's a big one and unwieldy and I did it with a manual `sed` but I'll see if I get results.

@Vaelatern  Thanks for helping debugging this issue that probably has been there over 10 years.

I will need more help as I am not yet able to reproduce this in the dracut test-suite.

1./ Can you please confirm that omitting nfs module (e.g. `-o nfs` on command line or `omit_dracutmodules+=" nfs "  is a workaround ? Does void-mklive needs nfs module to function properly ? 

2./ Speculatively would commenting out the following line in `dracut.sh` resolve it/make a difference ? 

```
#[[ "$dracutsysrootdir" ]] || [[ "$noexec" ]] || export DRACUT_RESOLVE_LAZY="1"  
```

The goal is to make sure that `DRACUT_RESOLVE_LAZY` is NOT set.

Thanks. We can try to detect musl (or ldd/ldconfig version/info) and do not set `DRACUT_RESOLVE_LAZY`. Is there a recommended way for void to do the detection ?

`ldd 2>&1 | grep musl` looks to function. Not recommended but.

Maybe just unset it for the nfs module?
