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.

 The generated libtool for building libstdc++ adds the -nostdlib option to the

 g++ command for linking but doesn't add -lgcc.  This causes a "hidden symbol"

 error when linking against the libstdc++ shared object.  This patch adds gcc

 to the list of libraries linked against when linking libstdc++.
