Unknown ABI used in --with-abi=lp64 when build Zfinx

Zfinx的编译报错，完全按照下面这个步骤来的：

branch： riscv-gcc-10.2.0-zfinx
commit: 66ae94a003c26721913c21a1b07e38a775770d74

$ git clone https://github.com/pz9115/riscv-gcc
$ cd riscv-gcc
$ ./configure --prefix=/opt/rv64zfinx/ --with-arch=rv64imaczfinx --with-abi=lp64 --with-abi=lp64 --with-multilib-generator="rv64imaczfinx-lp64--"
$ make
$ make install

make的时候报错，报错的信息：

Unknown ABI used in --with-abi=lp64
make[2]: *** [Makefile:4443: configure-stage1-gcc] Error 1
make[2]: Leaving directory '/home/cxo/repos/riscv-gcc'
make[1]: *** [Makefile:24483: stage1-bubble] Error 2
make[1]: Leaving directory '/home/cxo/repos/riscv-gcc'
make: *** [Makefile:999: all] Error 2

rvv1.0的测试报错：clang-13: error: invalid arch name 'rv64gcv1p0'

执行make vector时报错如下：

cxo@3a5cae203b0b:~/test/riscv-vectorized-benchmark-suite/_axpy$ make vector
/home/cxo/repos/llvm-project/build/install/bin/clang  -Wall --target=riscv64-unknown-elf -DUSE_RISCV_VECTOR  -march=rv64gcv1p0 -menable-experimental-extensions -O2  --sysroot=/home/cxo/opt/rv64/bin/riscv64-unknown-elf --gcc-toolchain=/home/cxo/opt/rv64/bin  -c -o src/utils.o src/utils.c
clang-13: error: invalid arch name 'rv64gcv1p0', unsupported version number 1.0 for experimental extension (this compiler supports 0.10) 'v'
make: *** [Makefile:18: vector] Error 1

llvm的源码仓库是： https://github.com/llvm/llvm-project
branch : main
commit: 14da287e18846ea86e45b421dc47f78ecc5aa7cb
（可能是代码太老了，我更新重试一下）

_axpy/Makefile配置如下：

#makefile
