scripts: add option to strip all toolchain executables
To reduce filesizes of the toolchain and even improve build times of projects to be build with this toolchain it is usefull to strip the delivered toolchain executables. Since it is not likely that we will debug the toolchain executables itself we do not need the debug information inside the executables itself. Signed-off-by: Remy Bohmer <linux@bohmer.net>
