Normally control-u is bound to tty driver kill.  Because of there is a
tty driver value for ^U that value always overrides any readline
binding.  But if ^U is remove from the tty driver setting then it
won't.

There isn't a portable way to unset these values in the tty driver but
with GNU stty setting a value to "undef" will undefine it.

  stty kill undef

Having done this configuration to free up C-u it can then be bound
normally to whatever function is desired.

Note that undefining a tty editing character with stty makes it unavailable
to all programs you run.  Programs that don't use readline to read input
will not be able to perform the function the tty editing key is intended
to provide.
