This is an issue that is not specific to the Raspberry Pi 4B or even
arm64, but can be reproduced on amd64. It affects all 32-bit emulated
target when running PIE binaries. This has been fixed in qemu 5.0 by the
following upstream commit:

https://git.qemu.org/?p=qemu.git;a=commit;h=6fd5944980f4ccee728ce34bdaffc117db50b34d

This is definitely not a glibc bug. I am therefore reassigning the bug
to QEMU. Note that you might fix the issue by installing a recent
version of qemu-user-static in your chroot.
