[ Upstream commit f5c68a4e84f9feca3be578199ec648b676db2030 ]
There is a GCC crash bug in the randstruct for latest GCC versions that is being tickled by landlock[1]. Temporarily disable GCC randstruct for COMPILE_TEST builds to unbreak CI systems for the coming -rc2. This can be restored once the bug is fixed.
