No ip command does not call bridge.

More likely either your kernel is out of date with the ip command (ie new ip command is asking for
something kernel doesn't understand); or the iplink_bridge.c was not compiled as part of your compile;
or simple PATH issue
or your system is not handling dlopen(NULL) correctly.

What happens is that the "type" field in ip link triggers the code
to use dlopen as form of introspection (see get_link_kind)
