how to build linux kernel with `allyesconfig` and debug information

I want to build a linux kernel with as many C source files as possible for testing, so I use make allyesconfig at first. Meanwhile I need debug info, so I tried some ways to add it:

  1. make menuconfig and open the debuginfo option.
  2. modify the "CONFIG_DEBUG_INFO_NONE=y" to "CONFIG_DEBUG_INFO=y"

and then run make, however an error happen for the both two ways: "FATAL: modpost: vmlinux.o is truncated. sechdrs[i].sh_offset=572324920 > sizeof(*hrd)=64 make[1]: *** [scripts/Makefile.modpost:56: vmlinux.symvers] Error 1 make: *** [Makefile:1169: vmlinux] Error 2"

so I'm confused, how could I add debug info when I use the allyesconfig? The tested versions of my kernel is 6.0-rc6 and 6.0
