test: remove test suite
The test suite is now a developed in a separate git repository. See here: http://cgit.uclibc-ng.org/cgi/cgit/uclibc-ng-test.git The test suite should be just like every other software compiled with the cross-toolchain. In the past strange problems where found when the test suite got build in the toolchain creation step.
