The Linux kernel for arm64 uses `-pie -shared` for LDFLAGS when using KASLR
(kernel address space layout randomization).  Trying to link an arm64 Linux
kernel with CONFIG_RANDOMIZE_BASE=y or CONFIG_RELOCATABLE=y produces the
following error from lld:

ld.lld: error: -shared and -pie may not be used together
