We are simply running out of memory. I uploaded a temporary workaround for CI as #4651 , but let's keep this bug open.

@kv2019i With the workaround #4651 form Kai, CI now enables Zephyr SOF build on CNL/ICL/TGL-H with XCC, and APL stays with GCC

[lgirdwood]

@aiChaoSONG can we close ?

[aiChaoSONG]

@aiChaoSONG can we close ?

Let's keep this open, the workaround #4651 just skip the build of APL with xcc and zephyr, it doesn't workaround the build failure issue.
