Hello Stijn

I am currently working on a target for integration in Openwrt (Lightning 
Mountain).
This is a x86_64 architecture with 4 Atoms CPUs. I have added a new 
target (mxl) and
subtarget (lgm) with $(ARCH) x86_64.

But If I do it like this, then the module could not be build because,
the dependency is not met. "Missing

So far it only works now if I set the $(BOARD) value to x86 in the 
Makefile and
I also have to add a $(SUBTARGET) 64 in my directory mxl which in my 
case does not fit.

I also wanted to make it equal to the packages kmod-crypto-lib-poly1305.
This package maps this via $(ARCH) and doesn't do any special handling.

So I would prefer if we make it dependent on the $(ARCH) variable.
Also in the linux kernel this is also  under /arch/x86.

I think we should also update [1]
