Using clang's static analyzer is as simple as running "scan-build make",
but in order to obtain clean and reproducible results, the build
environment has to be cleaned beforehand ("make clean distclean").
Moreover the project requires running "make install" before "make test"
in order to install the dependencies needed for the tests, and running
these tests with the newly-built libraries requires a specific
LD_LIBRARY_PATH. This new script takes care of setting up everything
which is needed.
