…ephyrproject-rtos#14) Account for the zephyrproject/zephyr-intel vs zephyrproject/zephyr path to repo checkout. West needs to run against zephyr-intel dir and the quarantine list is also located down that path. That's the only difference between zphyr and zephyr-intel. So a simple check for a zephyrproject/zephyr-intel directory tells us which flavor we have, and sets a ZEPHYR_DIR var to use to toggle the path accordingly.

Flush all messages and invoke `abort()` when a k_panic() or k_oops() is hit in native_posix mode. One of the main purposes of `native_posix` is to provide debug convenience. When running in a debugger, `abort()` stops execution which provides a backtrace and the ability to inspect all variables. A practical use case is fuzzing failures in SOF, see an example in: thesofproject/sof#8632 In such a case, this commit adds value even before using a debugger.

Flush all messages and invoke `abort()` when a k_panic() or k_oops() is hit in native_posix mode. One of the main purposes of `native_posix` is to provide debug convenience. When running in a debugger, `abort()` stops execution which provides a backtrace and the ability to inspect all variables. A good, sample use case is fuzzing failures in SOF, see an example in: thesofproject/sof#8632 In such a case, this commit adds value even before using a debugger.
