kbuild: fix genksyms build error
genksyms needs to know when a symbol must have a "_" prefex as is
true for a few architectures.
Pass $(ARCH) as commandline argument and hardcode what architectures that
needs this info.
Previous attemt to take it from elfconfig.h was br0ken since elfconfig.h
is a generated file.
