  -----------
  Work around VNET and DPCPU related panics on aarch64

lld >= 14 and recent GNU ld can relax adrp+add and adrp+ldr
instructions, which breaks VNET and DPCPU when used in modules.

Until VNET and DPCPU can be fixed to deal with these relaxed
instructions, disable linker relaxation for now.
