[Tarantool-patches] [PATCH luajit 3/3] macOS: Remove obsolete -single_module flag.

[Sergey Kaplun via Tarantool-patches <tarantool-patches@dev.tarantool.org>]

From: Mike Pall <mike>

Thanks to dundargoc.

(cherry picked from commit 97813fb924edf822455f91a5fbbdfdb349e5984f)

The aforementioned flag is the default since Xcode 2.2 [1].
This patch removes this flag to avoid warnings for modern Xcode
versions at the linking stage.
