Ruby fails to build on macOS 12.6.4 when configured with --enable-shared and --with-jemalloc. I receive the following linking error:

building spec/ruby/optional/capi/ext/bignum_spec.bundle
Undefined symbols for architecture x86_64:
  "_je_free", referenced from:
      _bignum_spec_rb_big_pack_array in bignum_spec-f7dc36.o
  "_je_malloc", referenced from:
      _bignum_spec_rb_big_pack_array in bignum_spec-f7dc36.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [spec/ruby/optional/capi/ext/bignum_spec.bundle] Error 1

It appears that the bignum C API spec requires "-undefined dynamic_lookup" to be enabled. I can get the build to succeed with:

./configure --enable-shared --with-jemalloc DLDFLAGS='-Wl,-undefined,dynamic_lookup'

I’ve created several bash scripts to demonstrate that:

1. This is an error with the current production release of Ruby. Running jemallocBug-ruby3.2.2-20230407.sh demonstrates that building Ruby with these parameters fails in Ruby 3.2.2.
2. This is a regression in at least the Ruby 3.1 branch. Running jemallocSucceeds-ruby3.1.2-20230407.sh demonstrates that building Ruby with these parameters worked with Ruby 3.1.2 and running jemallocBug-ruby3.1.3-20230407.sh demonstrates that building Ruby with these parameters fails in Ruby 3.1.3.

In the Ruby 3.1 branch, the first commit where this broke appears to be 2244fc9aa7ef8e03ac966e59b581baa021106b46.

Please let me know if you need any more information.
