Hi all,

I got a below error message during building the musl with clang and -flto option.

- my build option was ./configure CC=clang CFLAGS="-fPIC -flto -O2".

- I also tried building with "CFLAGS="-flto -O2". However, the result was the same.

- I used clang 9.

This was my error message.

Could you please advise how I should handle this error?
