scripts/link-vmlinux.sh: force error on kallsyms failure
Since the output of the invocation of scripts/kallsyms is piped directly into the assembler, error messages it emits are visible on stderr, but a non-zero return code is ignored, and the build simply proceeds in that case. However, the resulting kernel is most likely broken, and will crash at boot. So instead, capture the output of kallsyms in a separate .S file, and pass that to the assembler in a separate step.
