Broken C compiler

[liamdiprose]

Version: Current HEAD of dev-esp32 (10d0a26f)

The build fails when checking for a working C compiler:

-- Check for working C compiler: /nix/store/bbs40g5kz34lc0aj0x8da1d8h7kpak4k-xtensa-esp32-elf-esp-idf-v5.1.2/bin/xtensa-esp32-elf-gcc - broken

The most likely cause in the error trace:
