# The modules_sign target checks for corresponding .o files for every .ko that
# is signed. This doesn't work for package builds which re-use the same build
# directory for every variant, and the .config may change between variants.
# So instead of using this script to just sign lib/modules/$KernelVer/extra,
# sign all .ko in the buildroot.
# This essentially duplicates the 'modules_sign' Kbuild target and runs the
# same commands for those modules.
