actually, looks like an easy fix. We just have to define DEFAULT_MACOSX_MIN_VERSION to the build OS version when building ld64 and we should be good:

/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_devel_ld64/ld64-127/work/ld64-127.2/src/ld/Options.cpp



	#ifdef DEFAULT_MACOSX_MIN_VERSION
			warning("-macosx_version_min not specificed, assuming " DEFAULT_MACOSX_MIN_VERSION);
			setMacOSXVersionMin(DEFAULT_MACOSX_MIN_VERSION);
	#else
			warning("-macosx_version_min not specificed, assuming 10.6");
			fMacVersionMin = ld::mac10_6;
	#endif
