Certain recent versions of the kernel.org crosstool toolchains were
built against a pretty recent glibc so attempting to run it on a system
with an older glibc will result in the error above:

https://lore.kernel.org/87mt2eoopo.fsf@xxxxxxxxxx/

Arnd resolved this and reuploaded the binaries, I suspect the Intel
folks need to mirror the updated tarballs to 01.org:

https://lore.kernel.org/e9601db2-ff7d-4490-abd5-8d3c5946e108@xxxxxxxxxxxxxxxx/

According to make.cross, you can override the URL it uses with a
variable, you could try removing these files

/root/0day/gcc-12.3.0-nolibc/s390-linux
/root/0day/gcc-12.3.0-nolibc/x86_64-gcc-12.3.0-nolibc_s390-linux.tar.xz

and running

$ COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-12.3.0 URL=https://mirrors.edge.kernel.org/pub/tools/crosstool/files/bin/x86_64 ~/bin/make.cross W=1 O=build_dir ARCH=s390 olddefconfig

to see if that works now.

Cheers,
Nathan
