New issue by Calandracas606 on void-packages repository

https://github.com/void-linux/void-packages/issues/44807

Description:
### Is this a new report?

Yes

### System Info

Void 6.3.10_1 aarch64-musl Unknown uptodate rFF

### Package(s) Affected

linux-headers-6.3_1

### Does a report exist for this bug with the project's home (upstream) and/or another distro?

_No response_

### Expected behaviour

installing a package that includes a DKMS module (eg. zfs, wireguard) builds the module successfully

### Actual behaviour

DKMS Module fails to build. Log files mention missing "arch/powerpc/crypto/Kconfig"


### Steps to reproduce

1. xbps-install zfs
2. Error

Comment:

/usr/src/kernel-headers-6.3.10_1/arch/powerpc is missing on aarch64, but this file exists on my x86_64 device

Device is a pinebookpro.
Same issue with aarch64-musl and aarch64-glibc

Linux package (mainline kernel) and Linux-headers are installed
Tested with using pinebookpro-kernel and pinebookpro-kernel-headers and this also fails

On my x86_64-glibc machine, trying to produce an aarch64 image using ./mkplatformfs in void-mklive also fails to build the zfs module with the same error.

As a note, `wireguard-dkms` shouldn't be used with any kernel after 5.5.

Comment:
I built natively the package linux6.3 on aarch64-musl. I don't get the error related to powerpc files anymore, so it's probably something related to cross-compilation.

I still can't build zfs, but I think this is an unrelated problem:

```

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
@@ -19,9 +19,7 @@
 
 export IGNORE_CC_MISMATCH=1

        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).

@sgn (you maintain the kernel package). Any idea why this could happen?
