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. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
