# Open-Source IPA shlibs need to be signed in order to be runnable within the

# while installing so we don't need to do it manually here.
# Buildroot may strip symbols, so we need to do the same before signing
# otherwise the signature won't match the shlib on the rootfs. Since meson
# install target is signing the shlibs, we need to strip them before.
