The __bb_init_func export is to allow modules to be built with a gcov-enabled UML. I get a bunch of undefines in the module links when I get rid of it.
This is probably being too intimate with libc, and yours probably doesn't have __bb_init_func.
Try the patch below and see if it helps. Modules won't work, but you should get a working UML.
