Hmm - I do not understand at all where `__bb_init_func' comes from (not from 
UML by sure, only from kernel headers possibly). And from preprocessing the 
source (of the -bk4 snapshot), nothing similar comes out.

long um_execve(char *file, char * *argv, char * *env)
{
 long err;

 err = execve1(file, argv, env);
 if(!err)
  do_longjmp((current_thread_info()->task)->thread.exec_buf, 1);
 return(err);
}

make arch/um/kernel/exec_kern.i ARCH=um

grep bb_init arch/um/kernel/exec_kern.i
gives nothing (tested with your config, too).

Try adding a "#undef execve1" before the problematic line, and reporting (here 
I don't get the failure).
