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.

<`Kumba> ths: given the SHN_UNDEF thing is a hack, what's the preferred solution?

<ths> For fakeroot the simplest trigger is "fakeroot file /bin/ls".

<ths> `Kumba: I haven't found a better one yet.

<ths> Probably marker symbols around the stub section, and then exclude it from the link map.

<ths> This needs a ld change.
