Work around XCode 14 issue with some native gems

What does this Merge Request do and why?

XCode 14 causes the Ruby interpreter to drop the -Wl,-undefined,dynamic_lookup flags in the DLDFLAGS, which are passed in the final step to link a shared library of a native gems. While this flag is still supported, the following warning causes the configure step to omit these flags:

ld: warning: -undefined dynamic_lookup may not work with chained fixups

This breaks some native gems, such as pg_query, thrift, and ffi-yajl, which can no longer find the symbols they need:

linking shared-object pg_query/pg_query.bundle
Undefined symbols for architecture arm64:
  "Init_pg_query", referenced from:
     -exported_symbol[s_list] command line option
     (maybe you meant: _Init_pg_query)
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Until https://bugs.ruby-lang.org/issues/19005 is resolved, restore these flags so that macOS users with XCode 14 can continue to function.

A reinstall of the Ruby interpreter is necessary to ensure RbConfig::CONFIG['DLDFLAGS'] contains these flags.
