Comment:
Actually the problem does not seem to be cross-compilation. This issue doesn't affect the natively built kernel package just because this one doesn't require the helper tools to be rebuilt.
If I make these changes:

```diff
--- /etc/kernel.d/post-install/10-dkms.old
+++ /etc/kernel.d/post-install/10-dkms

        yes "" | make -j $(nproc) -C /lib/modules/${VERSION}/build prepare0
-fi
 
 # Check available DKMS modules
 for _mod_ in /var/lib/dkms/*; do
```

then `xbps-reconfigure -f linux6.3` fails with the error mentioned by @Calandracas606, both with a cross-compiled kernel and a native one.
I tried the same thing on a x86_64 system and it fails too (even though the missing files are not the same).
