tcwg_kernel-build.sh: Use LLD for LLVM Linux kernel link jobs
It is expected that developers using clang to build the linux kernel
will also use LLD for the linker. We would like to test this in the LLVM
builds of the linux kernel as much as possible. To use LLD in the kernel
build we set LD=/path/to/linker when calling make.
At the moment we use LLD for llvm-*-aarch64-*-* builds and for
llvm-master-arm-*-* builds.
