That's a good point, yet was not reason for my issue :) It forced me to try with ARCH=arm
(and update toolchain)

$ CROSS_COMPILE=arm-none-linux-gnueabihf- make ARCH=arm mrproper
$ CROSS_COMPILE=arm-none-linux-gnueabihf- make ARCH=arm vexpress_defconfig
$ grep -w CONFIG_MODULES .config
CONFIG_MODULES=y
$ grep "=m" .config
$ echo $?
1
$ CROSS_COMPILE=arm-none-linux-gnueabihf- make ARCH=arm Image -j5 > /dev/null 
$ ls *.symvers
vmlinux.symvers
$ CROSS_COMPILE=arm-none-linux-gnueabihf- make ARCH=arm Image -j5 modules > /dev/null 
$ ls *.symvers
Module.symvers  vmlinux.symvers

So, `make modules` seems to become be mandatory. I'll go and update my scripts...

Cheers
Vladimir
