fix: Xcode15 upgrade

[whalelephant]

With the new update to Xcode 15, the current build causes this error on MacOS

  = note: ld: segment '__DWARF' filesize exceeds vmsize in '/<path>/libosmosistesttube.dylib'
          clang: error: linker command failed with exit code 1 (use -v to see invocation)

Details:

• This was described in https://github.com/golang/go/issues/50506
• A workaround to not generate the DWARF for debug was used -> https://github.com/Agoric/agoric-sdk/pull/8368

This follows the approach in the walk-around - not sure if we want to keep it the same for other OS.
