Michael,

is this a systemd machine ? If yes: We had the same problem before some days in our Gentoo forum:

https://forums.gentoo.org/viewtopic-t-1162393.html

Here it was SystemCallFilter from systemd.

Regards,
Peter

It's only been a couple of weeks since I updated this system, so I don't
know
why it fails with a glibc update, while other systems have no problem:

[...]

* The specific snippet of code:
* [[ $STAT -eq 0 ]] || die "CONFIG_IA32_EMULATION must be enabled in the kernel to compile a multilib glibc.";
*

The kernel has IA32_EMULATION compiled in:

# grep IA32_EMULATION /usr/src/linux/.config
CONFIG_IA32_EMULATION=y

and /lib/libdl.so.2 appears to be present and correct:

$ ls -l /lib/libdl.so.2
-rwxr-xr-x 1 root root 13660 Nov 20 13:59 /lib/libdl.so.2

So, why does it fail and more importantly ... how can I get past it? ;-)

Thanks Peter, no this is a openrc system. I don't even understand what a SystemCallFilter thing is ... :-/

Small nit-pick: Is it enabled in the kernel that is actually running?  

zgrep CONFIG_IA32_EMULATION /proc/config.gz

and /lib/libdl.so.2 appears to be present and correct

Is the file (or the filesystem, or the disk) possibly corrupted? The
"cannot real file data: Input/output error" is troubling. I would try
fsck'ing the file system from a live USB if possible.

I don't have IKCONFIG in the kernel, but I did check in the first instance which kernel I had booted with.

Yes! This was the problem. I have a corrupted partition and all sort of
files can't be accessed. :-(

Now to see how old the backup I have is and take it from there. Thanks for pointing me in the right direction.
