[Buildroot] [PATCH v2 1/1] gmock: new package

[Carlos Santos]

Inspired by jMock, EasyMock, and Hamcrest, and designed with C++'s
specifics in mind, Google C++ Mocking Framework (or Google Mock for
short) is a library for writing and using C++ mock classes.

Google Mock:

  * lets you create mock classes trivially using simple macros,
  * supports a rich set of matchers and actions,
  * handles unordered, partially ordered, or completely ordered
    expectations,
  * is extensible by users, and
  * works on Linux, Mac OS X, Windows, Windows Mobile, minGW, and
    Symbian.

There are both host and target packages. The target one has include
files required to compile the tests and the static libraries required
to link/run them. The host package installs gmock_gen, a Python script
used to generate code mocks.
