Please help check configuration to buld musl targeting risc-v

[Chen Wang]

Hello,
I am trying to build musl with clang for risc-v.

Following is my configuration input:

ARCH=riscv \
CROSS_COMPILE=riscv64-unknown-linux-gnu- \
CFLAGS="-v --gcc-toolchain=/opt/riscv64 --sysroot=/opt/riscv64/sysroot/" \
CC=../../llvm-project/install/bin/clang \
./configure --prefix=/home/u/ws/test-musl/install --exec-prefix=/home/u/ws/test-musl/install --disable-shared

"../../llvm-project/install/bin/clang" is what my clang locates, it is 10.0.1 and built by me from source, it's configured for RISC-V and I have used it to built execuation and it works well.
"/opt/riscv64" is the path where my gnu toolchain locates.

After configraton, I run make and it makes llvm/clang oops when compile "src/complex/catan.c". 
> clang-10: error: clang frontend command failed due to signal (use -v to see invocation)

It looks like an issue from llvm, but before I submit this issue to llvm, I just want to double check here if my configration is ok for building musl with clang and target for risc-v.

Thanks in adv.

Please post musl questions to the musl list:

I don't know the LLVM policy about compiler crashes, but I suspect
they would want to learn about them, especially if you can provide a
preprocessed source file that reproduces the crash.
