bisect says after commit:

commit 71b849f18c6af931a004754b3ebf76a5c1dfa715

    cmake: Port Zephyr to use zephyr_check_compiler_flag
    
    This commit ports nearly all usage of check_c_compiler_flag,
    check_cxx_compiler_flag, and check_compiler_flag to use
    zephyr_check_compiler_flag instead.
    
    This has a significant CMake configure-time performance impact.

actually this is failing with other toolchains as well, i.e. issm toolchain and xcc.

"doesn't work for me:"

Strange. It works on my machine.

Could you try clearing the cache? rm -rf /home/inaky/.cache/zephyr

Also, make sure you have a clean git status and clean build directory.

    cmake: Suppress messages about compiler checks
    
    Messages about compiler checks are very verbose so we disable them by
    default. They have always been undesirably verbose, but introducing
    CMAKE_REQUIRED_FLAGS into the 'check' string made them unacceptably
    so.

@inakypg : Please dump the cache file (after clearing it and re-running CMake).

And also place

print(key)

in cmake/extensions.cmake/zephyr_check_compiler_flag

and a

message("Cache miss")

at the end of the function.

cmake: Introduce a key version to invalidate corrupted caches
3c3450d 
When a bug in the caching mechanism is detected the cache format must
be bumped to ensure that we no longer get a cache hit on old corrupted
keys.

This fixes zephyrproject-rtos#7246 when the cache is corrupted.

The root cause for the failure after the fix has been applied has been identified. Another fix has been pushed to the same PR.

"doesn't work for me:"

Strange. It works on my machine.

Could you try clearing the cache? rm -rf /home/inaky/.cache/zephyr

For however comes across this thread with the error xtensa-esp32-elf-gcc: error: unrecognized command line option '-m32'. The above fixed this too. thanks @SebastianBoe !
