Thanks.  Any updates to doc/README.clang would be good.  It looks like
there's still a large number of blocking problems on aarch64 for someone
to solve (no libgcc, but could we just solve that another way?) and
linking U-Boot itself fails, but maybe we can use the clang linker by
now?

On both 32 and 64bit ARM, EFI loader needs to be disabled for rpi at
least to finish compiling, and on 32bit it does link and run.
