Summary: trunk head toolchain gcc test fails by runnning on trunk head kernel

Details:

trunk head toolchain gcc test fails by runnning on trunk head kernel now. It would make kernel panic and restart.

It is not specific to certain gcc case, and would have different dump errors.

On bf527 board:

testing uclinux gcc
