WORKS)

Ingo, this breaks cross compiles because kallsyms expects a host
executable:

$ /sbin/kallsyms .tmp_vmlinux > .tmp_kallsyms.o
.tmp_vmlinux: ELF file .tmp_vmlinux not for this architecture

You can't even do $(CROSS_COMPILE)kallsyms because that isn't part of
most peoples toolchains. (and /sbin might not be in the $PATH).

I'm not sure what kallsyms does *exactly* but it sounds like the same
functionality can be had from objcopy...
