    Work around VNET and DPCPU related panics on aarch64

    lld >=3D 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.
