Cross-build issues over bookworm host for non-bookworm targets

[Jan Kiszka <jan.kiszka@siemens.com>]

Hi all,

the kas-isar:next build container is now based on bookworm, and that 
seems to reveal some issues around cross-building over that host. I've 
not reproduced that with two layers, meta-iot2050 and isar-cip-core. The 
latter builds fine natively, e.g. qemu-amd64, but it fails once 
switching to qemu-arm64 e.g. BUT: bookworm as target is fine again.

Some exemplary splat:

"/lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found", that looks suspicious.

Are we leaking something from the host into the sbuild env that falls 
apart here? Are we missing a dependency for the sbuild env? Or is there 
a fundamental incompatibility in bookworm?
