`obj2yaml` does not seem to preserve dependency information for ELF shared libraries

When converting an ELF shared library (`.so`) to YAML using `obj2yaml` and then back to a `.so` using `yaml2obj`, the `NEEDED` entries do not appear to be preserved as expected. Instead of the shared library names, the output shows numeric values.
I am not sure if this is the intended behavior or a missing feature/bug.
**Steps:**
```bash
# Original .so has dependencies:
0x0000000000000001 (NEEDED) Shared library: [libA.so]
0x0000000000000001 (NEEDED) Shared library: [libB.so]
0x0000000000000001 (NEEDED) Shared library: [libD.so]
0x0000000000000001 (NEEDED) Shared library: [libZ.so]
# Convert original .so → yaml → new .so
obj2yaml original.so > lib.yaml
yaml2obj lib.yaml > new.so
# New .so shows:
# readelf -d libC.so | grep NEEDED
0x0000000000000001 (NEEDED) 0x6e
0x0000000000000001 (NEEDED) 0x76
0x0000000000000001 (NEEDED) 0x7e
0x0000000000000001 (NEEDED) 0x86
```
**Environment:**
* Host: macOS (Apple M1)
* Running inside Docker:
```bash
docker run --platform=linux/amd64 -it --rm -v $(pwd):/workspace ubuntu:22.04
```
* LLVM version: `22.0.0git` (built inside Docker)

Is this the expected behavior for `obj2yaml`/`yaml2obj` with ELF?
