  On OS X systems, this creates a Macintosh package and disk image in which the
  libjpeg-turbo static libraries contain ARM architectures necessary to build
  iOS applications.  If building on an x86-64 system, the binaries will also
  contain the i386 architecture, as with 'make udmg' above.  You should first

-  the ARM v7s build under {source_directory}/iosarmv7s by default, and (if
-  applicable) the 32-bit build under {source_directory}/osxx86 by default, but
