Sometimes, the `ld-linux` shared object is presented as an absolute
path, instead of the shared object name and the path where that shared
object is found.
Something like this:
```
$ ldd /nix/store/s7cjsl5g5hdi4lfmb5qghghgni69ch1y-coreutils-full-9.7/bin/true
linux-vdso.so.1 (0x0000ffffb47fc000)
libcrypto.so.3 => /nix/store/ffdmy5fhjr6m1gkb8mycyf3swakvygd1-openssl-3.4.1/lib/libcrypto.so.3 (0x0000ffffb4240000)
libacl.so.1 => /nix/store/ccy32hi8wvjj1im3dbjld658rpvl226n-acl-2.3.2/lib/libacl.so.1 (0x0000ffffb4210000)
libattr.so.1 => /nix/store/3fqsrmsjdpfpy6dyxymbg6r01f9y39ln-attr-2.5.2/lib/libattr.so.1 (0x0000ffffb41e0000)
libgmp.so.10 => /nix/store/xmdlv9xmhyiqip377326ph94k1ipndz2-gmp-with-cxx-6.3.0/lib/libgmp.so.10 (0x0000ffffb4140000)
libc.so.6 => /nix/store/7kpxf47mzykkdn39lcnhj9z9ngpihamf-glibc-2.40-66/lib/libc.so.6 (0x0000ffffb3f60000)
/nix/store/7kpxf47mzykkdn39lcnhj9z9ngpihamf-glibc-2.40-66/lib/ld-linux-aarch64.so.1 (0x0000ffffb47c0000)
libdl.so.2 => /nix/store/7kpxf47mzykkdn39lcnhj9z9ngpihamf-glibc-2.40-66/lib/libdl.so.2 (0x0000ffffb3f30000)
libpthread.so.0 => /nix/store/7kpxf47mzykkdn39lcnhj9z9ngpihamf-glibc-2.40-66/lib/libpthread.so.0 (0x0000ffffb3f00000)
```
Here, because the line with `ld-linux-aarch64.so.1` does not have the
pattern `=>`, it gets excluded and the binary execution (with the
`--ldd` flag) fails due to a permissions error.

I think I prefer #38 for this, thoughts? |

Wasn't aware of #38. Let me test it on my machines and I'll get back. |

@thefossguy are you happy with #38? should we close this one? |

@Zouuup There's still another problem of only absolute SO paths being whitelisted. |
