Hello Jeff,
Thanks! But when I update the config as you suggest:
AR=/usr/local/bin/llvm-ar \
RANLIB=/usr/local/bin/llvm-ranlib \
CC=/usr/local/bin/clang \
CFLAGS="--rtlib=compiler-rt --target=aarch64" \
ASFLAGS="-Wa,--noexecstack" \
LDFLAGS="-Wl,-fuse-ld=/usr/local/bin/ld.lld --rtlib=compiler-rt --target=aarch64" \
LIBCC=-lcompiler_rt \
./configure --target=aarch64 \
&& make
It still reports the error as below:
[cid:919d9698-56e2-49d2-85c5-8b12ac33e65f]
Another question, if I want to use LLVM tool chain instead of GCC, how should I config? Acutally I don't understand why there is gcc error, because I have specify to use clang and ld.lld.
Thanks,
Simon

-fuse-ld=/usr/local/bin/ld.lld is a LDFLAG. Since you are using GCC to drive link, set:
LDFLAGS = "-Wl,-fuse-ld=/usr/local/bin/ld.lld "
--rtlib=compiler-rt and --target=aarch64may need to go into LDFLAGS, too.
--noexecstack is a ASFLAG. Use:
ASFLAGS = "-Wa,--noexecstack"
