mips allmodconfig build error with llvm-18.1.7-x86_64

[Jeff Johnson <quic_jjohnson@quicinc.com>]

As part of my tree-wide cleanup of missing MODULE_DESCRIPTION() macros I'm
trying to do allmodconfig builds for every architecture.

With:
export ARCH=mips
export LLVM=llvm-18.1.7-x86_64/bin/
make distclean
make allmodconfig
make -j$(nproc)

I'm getting build errors like:
Cannot find symbol for section 46: .text.free_initmem.
init/main.o: failed

Cannot find symbol for section 6: .text.copy_from_kernel_nofault_allowed.
mm/maccess.o: failed

Cannot find symbol for section 10: .text.arch_asym_cpu_priority.
kernel/sched/fair.o: failed

Interestingly, if I make 'defconfig' instead of 'allmodconfig' I don't see
this issue.

Any thoughts on how to have a successful mips allmodconfig build?
