to the makefiles in the examples and miniapps directories.
In the top-level makefile:
* the target 'all' will also build the unit tests
* the target 'test' will also run the unit tests
* removed the target 'alltest' (now it is the same as 'test')
In .travis.yml, since the 'test' target will run the unit tests,
remove the special Travis CI build that just runs the unit tests.
