Hi Weiming,

Did you use the -triple as "aarch64-elf"? On ARM, I found that this is
all you need to get the driver to find the right tools. I haven't
needed to use -gcc-tools or anything.

Also, be careful that bare-metal GNU toolchains are also bare. You'll
need to add -l* to all libraries that you need, maybe include paths,
etc.

cheers,
