Hello Markus,
Thanks!
AR=/usr/local/bin/llvm-ar \RANLIB=/usr/local/bin/llvm-ranlib \CC=/usr/local/bin/clang \CFLAGS="-fuse-ld=/usr/local/bin/ld.lld --rtlib=compiler-rt --target=aarch64" \LIBCC=-lcompiler_rt \./configure --target=aarch64 \&& make
But when I use the above config, it reports the below error, but I don't understand why there are gcc error, I have explict specify to use clang and ld.lld
