RTLD_GLOBAL was used to allow plugins use each other symbols but this
facility was (most likely) never used and is a bad design anyway. If
there is a common code it should just go to a library.
Using RTLD_LOCAL on the other hand saves us from conflicting symbols
used by different plugins. An example can be iwinfo plugin using libnl.
If there appears to be another plugin using incompatible netlink
implementation this will result in a problem. Both plugins will start
using the same libnl which will break one of them.
