Hello,
Context: https://github.com/ugexe/zef/issues/457#issuecomment-1586021352
I'm not familiar with how `ld` works so I'm not sure how to create a
minimal reproducible example.
- zef is Raku's module manager
- Raku: formerly Perl 6
When I try to run `zef install --debug Crypt::Bcrypt` it always fails in
build step with this error:
```

```
This is how `ld` is invoked, the issue seems to be with '%' in directory
name:
```
andinus@cadmium /t/.z/1/D/raku-digest-sha1-native-master> "/usr/bin/ld"
--eh-frame-hdr -Bdynamic -shared -o

```
Quoting the path doesn't work, even escaping '%' with \ doesn't seem to
work. What works is removing % from path altogether.
Here is ktrace output:

If you notice the 2nd `NAMI`:
```
23633 ld NAMI
"/tmp/.zef/1686382217.68953/Digest%3A%3ASHA1%3A%3ANative%3Aver%3C0.06%3E%3Aauth%3Cgithub%3Abduggan%3E.tar.gz/raku-digest-sha1-native-master/resources/libraries/libsh\
a1.so"
...
23633 ld NAMI
"/tmp/.zef/1686382217.68953/Digest73A43ASHA143A73ANativef3Aver73C0.0613E23Aauth73Cgithuba3Abduggan13E.tar.gz/raku-digest-sha1-native-master/resources/libraries/libsh\
a1.so.tmpc5eb445"
```
ld seems to interpret those '%' weirdly, it turns them into some
alphanumeric character.
I suspect this might be what is causing this issue.
