Error when building for esp32c3_devkitm

[joaomcfreire]

Describe the bug
Building the hello world sample for ESP32C3 gives an error. See logs below.

I'm on macOS Monterey 12.5.1 on a Macbook Pro 2017.

To Reproduce
Steps to reproduce the behavior:

1. Follow the steps for macOS in Getting Started and Supported Boards - ESP32C3
2. Activate Virtual Env.
3. Go to ~/<zephyr_repository
4. Run west build -b esp32c3_devkitm samples/hello_world -p
5. See the error in the logs output of this report.

Expected behavior
I would expect it to build like it does when I build for esp32, qemu_x86 or qemu_xtensa.

Impact
Blocking learnings about Zephyr OS

Additional context

Seems like I'm missing some dependency to build for RISCV platforms as trying to build for qemu_riscv32 also gives the same error.

It looks like you have a broken toolchain installation.

Please make sure that risv64-zephyr-elf directory exists under /Users/joaofreire/zephyr-sdk-0.15.0 and that it contains libgcc.a
