Noel Eck 0bd68e4e2b ANDROID: CMake/src changes to build on android-24
* Updated pom file generation: Generate pom files after all sensor
      library targets have been created - allows for dependencies
    * Changes for compiling on Android
    * Check for mraa build options: Look at symbols in mraa library to
      determine UPM build options (example: mraa_iio_init, mraa_firmata_init)
    * Add per target summary for C/C++/java/nodejs/python
    * Added hierarchy to fti include directory...
        old: #include "upm_voltage.h"
        new: #include "fti/upm_voltage.h"
    * Removed unimplemented methods from mpu9150 library and java example
    * Add utilities-c target for all c examples.  Most of the C examples
      rely on the upm_delay methods.  Add a dependency on the utilities-c
      target for all c examples.
    * Updated the examples/CMakeLists.txt to add dependencies passed via
      TARGETS to the target name parsed from the example name.  Also updated
      the interface example names to start with 'interfaces'.
    * Updated src/examples/CMakeLists.txt to ALWAYS remove examples from the
      example_src_list (moved this from end of function to beginning).
