Errors when running build steps

[chiachia36]

Hi,
Here is my command before make.
../configure --prefix=$RISCV_TOOLCHAIN_ROOT_32 --host=riscv32-unknown-elf --with-arch=rv32i
Here is error message I got.

../pk/entry.S: Assembler messages:

Here is tool list in $RISCV_TOOLCHAIN_ROOT_32/bin.

Did I miss any steps?
Thanks!

I'm just shooting in the dark here, but you might need to add $RISCV_TOOLCHAIN_ROOT_32/bin to your PATH before executing configure. If configure can't locate the RISC-V compiler, it'll end up using your host compiler.

It seems the problem is mentioned at riscv-collab/riscv-gnu-toolchain#1053. I revert my riscv-gnu-toolchain to tag:2022.03.09.
