# Open-Source IPA shlibs need to be signed in order to be runnable within the
# same process, otherwise they are deemed Closed-Source and run in another
# process and communicate over IPC.
# Buildroot sanitizes RPATH in a post build process. meson gets rid of rpath
# 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.
