# A bug in ld prevents us from having a (constant-value) symbol in a
# "ORIGIN =" or "LENGTH =" expression. We fix that by generating a
# linker file with the symbolic part of those expressions evaluated.
# 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.
