[Tarantool-patches] [PATCH luajit 3/5] Disable unreliable assertion for external frame unwinding.

[Maxim Kokryashkin via Tarantool-patches <tarantool-patches@dev.tarantool.org>]

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.

Maxim Kokryashkin:
* added the description for the problem
