-# Unfortunately, there is trouble making vmlinux depend on anything we
-# generate here, so we *always* regenerate the final linker script and
-# replace the LD macro to get what we want. Thankfully(?) vmlinux is
-# always rebuilt (due to calling make recursively and not knowing if
-# anything was rebuilt).
-# The shell script to build in some kind of dependency is really not
-# necessary for reasons of speed. It's there because always
-# regenerating stuff (even for incremental linking of subsystems!) is
-# even more nauseating.
