Re: [PATCH v2] linux-custom: Fix decompressed kernel name for arm64

[Henning Schild <henning.schild@siemens.com>]

Turns out this is wrong. debian itself would use vmlinuz for arm64 and
in fact also does that i.e in "linux-update-symlinks" which takes its
"stem" from 

https://salsa.debian.org/kernel-team/linux-base/-/blob/master/lib/DebianLinux.pm#L79

And on the other side of the story ... debians kernel build sets the
arm64 stem

https://salsa.debian.org/kernel-team/linux/-/blob/master/debian/config/arm64/defines#L14

I will send patches.
