arm64 variant ldd probe failure

[nightah]

It seems when utilising the existing tooling within the repository that the shared output file generated by this script for arm64 results in the following error during a probe with ldd (on a newer version of Ubuntu 24.04):

root@ef50510feddf:/tmp/su-exec# ldd su-exec-glibc-shared-arm64-14.04
ldd: exited with unknown exit code (139)

To be clear it still appears that the binary works as expected. I did notice if the builds are done with ubuntu:22.04 this error goes away.
