Request for Review: Make the Queens test ("test in build") an option that can be disabled

[Magnus Ihse Bursie]

As part of the new build system created in the build-infra project, we 
want to make it a configurable option wether or not to run the Queens 
test as part of the build.

Here is a patch that introduces a new make variable, TEST_IN_BUILD, 
which controls wether to run the Queens test (test_gamma.sh) or not. If 
the variable is not explicitely set, it will default to true, mening 
that the default behaviour will be as before, that is, to run the Queens 
test. However, if you (or configure) explicitely set it to false, the 
Queens test will be skipped.
