Error: .vector_table section is missing on ESP32-C3

[TheButlah]

Describe the bug
Flashing firmware for ESP32-C3 fails with an error. This happens regardless of whether the direct-boot feature is provided to the esp-hal (direct-boot bypasses the second stage bootloader on the esp32c3).

Cargo flash works, although it only works in direct-boot mode due to probe-rs/probe-rs#1194

To Reproduce

❯ probe-run --chip esp32c3 target/riscv32imac-unknown-none-elf/debug/firmware
Error: `.vector_table` section is missing

Expected and observed behavior
Expected the program to flash successfully.

I'm afraid we don't support RISC-V at the moment
