[PATCH 2/4] gcc-cross: Add cross testing driver for running regression testsuites

This script will be generated into the build directory of gcc-cross
It should be testing gcc and g++. libstdc++ tests are not run since
we build them as part of gcc-runtime but we can test them here by
building them with 'make all' and then running the tests

The script expects passwordless ssh access to target and is used
in form

./arm-oe-linux-gnueabi-testgcc kraj@192.168.7.2

inside the builddir of gcc-cross
