Exclude this test when using the Ninja generator for now.

For an unknown reason, touching the gen1_input.txt regenerates
the generated.txt file and that triggers re-running rcc and
re-generating qrc_res1_gen.cpp, however, that cpp file is not
compiled and linked into the exe until the next time ninja is
run.
Add a glob for debugging.
Ensure that the initial build works.
Add debugging information for the autorcc_depends test.

The test_res1 target should not be re-built at this point because
its dependencies have not changed. Test whether the test_res1 target
is just built every time make is run.
