Yes, runing as root is dangerou. For example, Buildroot as part of the
build process, runs 'rm' at some points, and even though we are trying
to be safe, bugs happen. Also, packages might do dirty things (e.g.
install in /usr/lib instead of $(DEST_DIR)/usr/lib ) and that would
break your system.

So no, running as root is really, definitiely not good at all.

Can you report on the output of:
    $ ldconfig --version

Can you try this patch, please:

diff --git a/Makefile b/Makefile
