[Tarantool-patches] [PATCH luajit 5/6] OSX/ARM64: Disable unwind info.

[Maksim Kokryashkin]

From: Mike Pall <mike>

See LuaJIT/LuaJIT#698.

(cherry picked from commit 78350a2565e1cf1102bcd25be406f02953d4dd3b)

External unwinding support is already disabled for OSX on ARM64
platfrom so there is no point in generation of incorrect unwind
info for it. This patch disables that generation.

Maxim Kokryashkin:
* added the description for the problem

Needed for tarantool/tarantool#6096
