I don't think this is specific to a particular randconfig.

On ARM allmodconfig, I saw:

ERROR: "__aeabi_uldivmod" [fs/xfs/xfs.ko] undefined!

On powerpc with an older gcc-4.5 toolchain, I saw:

/bin/sh: line 1: 23453 Segmentation fault      powerpc-linux-ld -EB -m
elf64ppc -r -T /home/paul/git/linux-head/scripts/module-common.lds
arch/powerpc/lib/crtsavres.o --build-id -o fs/xfs/xfs.ko fs/xfs/xfs.o
fs/xfs/xfs.mod.o
make[2]: *** [fs/xfs/xfs.ko] Error 139

I have not investigated further than that.

Paul.
