eglibc-testing: Clean the test before running them

We make sure that we use final cross gcc to run the tests
since they require proper functioning libstdc++ and libssp
which are not staged in tcbootstrap sysroot

We cleanup the tests before we run them so they all
get run in case any of them were built and/or run during compilation

Make the script executable

Add more documentation to diagnose setup problems
