I am using gcc version 11.3.1 20220517 (GCC). And I am not just building
spear3xx_defconfig, I am building all the arm configs with the same
compiler in the same setup and only spear3xx_defconfig started failing.
I am attaching a build summary report generated on 26th May, all arm builds
passed, even allmodconfig.

And, just to verify its not my setup or the compiler I use, I took a fresh
Debian Bullseye docker, installed 'gcc-arm-linux-gnueabi' from Debian and I see
the same build failure with spear3xx_defconfig. This gcc from Debian Bullseye
is: gcc version 10.2.1 20210110 (Debian 10.2.1-6).
