That failure is is due to newlib files:
/work/home/jzzhong/work/toolchain/riscv/build/dev-rv64gcv_zvfh_zfh-lp64d-medany-linux-spike-debug/../../*newlib*/newlib/libm/complex/ccoshl.c: 
In function 'ccoshl':

To build gcc w/ glibc with riscv-gnu-toolchain, run make linux.

A temporary fix for newlib is here:
