This happens on `x86_64-musl` but not on `x86_64`

Comment:
Ok, so trying to run `/lib/libc.so /lib/libglslang.so` also complains about the missing symbols, but it's clearly dynamically loaded in applications such as mpv, since it can be seen in the output of `/proc/$PID/maps`. This looks like a potential difference between symbol resolution when loading something directly and when loading something as a dynamic library.

Not sure it's a linking / binutils bug or a musl bug.

We might have some wrong linkage in `libHLSL`, at least:

```
$ env LD_PRELOAD=/lib/libglslang.so ldd /lib/libHLSL.so
	ldd (0x7f9a4211c000)
	/lib/libglslang.so => /lib/libglslang.so (0x7f9a41ebc000)
	libstdc++.so.6 => /lib/libstdc++.so.6 (0x7f9a41c25000)
	libc.so => ldd (0x7f9a4211c000)
	libHLSL.so => /lib/libHLSL.so (0x7f9a41b7b000)
	libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x7f9a41b62000)

`libglslang.so` doesn't provide stable ABI, but they declined to version their shared object.

Nothing we can really act on, I think... Can be reopened if a bug appears due to it.

Closed issue by st3r4g on void-packages repository

https://github.com/void-linux/void-packages/issues/23131

Description:
Bug in some libraries provided by `glslang`

### Steps to reproduce the behavior

`ldd /lib/libglslang.so`
```
Error relocating /lib/libglslang.so: _ZN7glslang12GlslangToSpvERKNS_13TIntermediateERSt6vectorIjSaIjEEPN3spv14SpvBuildLoggerEPNS_10SpvOptionsE: symbol not found
Error relocating /lib/libglslang.so: _ZNK3spv14SpvBuildLogger14getAllMessagesB5cxx11Ev: symbol not found
```

`ldd /lib/libHLSL.so`
```
Error relocating /lib/libHLSL.so: _ZN7glslang13TIntermediate8addCommaEPNS_12TIntermTypedES2_RKNS_10TSourceLocE: symbol not found
Error relocating /lib/libHLSL.so: _ZN7glslang13TInfoSinkBase6appendEPKc: symbol not found
... (long list)
Error relocating /lib/libHLSL.so: _ZTVN7glslang9TVariableE: symbol not found
Error relocating /lib/libHLSL.so: _ZTVN7glslang16TIntermSelectionE: symbol not found
```

This doesn't seem to break any program using them at the moment.
