It likely can be applied to all elf targets.  So yes, we probably need
to patch all templates that also discard *(.note.GNU-stack) and
*(.gnu_debuglink).  As I can't test them I didn't patch them - to me
it looks like pieces of that scripts should be moved to a common
sub-template ...

Thanks for applying the patch.

Richard.
