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.

     4 If gcc is configured to generate i686 code or better by default (like 

     5 when using the --with-arch=pentium3 configure option), then the __i686

     6 macro will always be defined automatically and thus screw up the

     7 compilation of some .S files.
