From: Mike Pall <mike>

Broken on Fedora/ARM64. Reported by Yichun Zhang.

(cherry-picked from commit e957737650e060d5bf1c2909b741cc3dffe073ac)

This patch disables the assertion that failed because of
incorrectly constructed unwind information.
That debug info generation was fixed in the scope
of tarantool/tarantool#6096. This patch is backported
only for consistency.
