[oe] [PATCH 2/2] kernel.bbclass: pass AR, NM and OBJCOPY to make

[Andreas Oberritter]

- Fixes build with certain vendor-supplied Montavista kernels.
- Pass the same set of variables to every invocation of make.
- Create KERNEL_*SUFFIX, TARGET_*_KERNEL_ARCH and HOST_*_KERNEL_ARCH
  for the three variables, analogue to LD.
