Comment (by Ionic):

 > We can see in the log that this line is invoking the compiler without
 specifying the necessary `-arch` and `-stdlib` flags:

 The `-stdlib` flag shouldn't be necessary. Note that this call is merely
 merging multiple object files into one big one (and skipping linking
 against other libraries, including a standard library, explicitly via
 `-nostdlib`).

 It's questionable why libtool would link individual object files into a
 big one prior to creating the dylib, but we'll have to live with that
 behavior.

 Creating object files with `-r` and without `-arch` flags will however
 only leave default-arch symbols in the resulting thin object file -
 exactly what is happening here.

 [[br]]
 The question thus is why libtool is dropping `-arch` flags from this
 linking call exactly. It does use -arch flags for other link operations,
 so it's unlikely to be caused by its intentional dropping of unknown
 `LDFLAGS`.


 Changing to the `muniversal` `PortGroup` likely won't help either, since
 the i386 build objects would likewise be dropped within the i386 build
 process.
