Every time we run make in a v3 tree, lar, lzma, nrv2b and the option

Browse source 
table get rebuilt unconditionally due to slightly incorrect
dependencies.
That's wasteful and may hide other dependency bugs.
Fix the lar, lzma, nrv2b and option table dependencies.

This trims down recompilation time a lot. The only remaining stuff being
rebuilt is:
~/corebootv3-better_dependencies> make
  CP      build/config.h
  GEN     build/build.h
  LAR     build/coreboot.rom
  PAYLOAD none (as specified by user)
  CP      build/bios.bin
  DONE
