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.

     1 Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/53_all_gcc4-superh-default-multilib.patch
     2 The gcc-3.x toolchains would contain all the targets by default.  With gcc-4,
     3 you have to actually list out the multilibs you want or you will end up with
     4 just one when using targets like 'sh4-linux-gnu'.
     5 
     6 The resulting toolchain can't even build a kernel as the kernel needs to build
     7 with the nofpu flag to be sure that no fpu ops are generated.
     8 
     9 Here we restore the gcc-3.x behavior; the additional overhead of building all
    10 of these multilibs by default is negligible.
