Description:
Allow boot entry to start with label instead of menu_label.
.
menu_ptr->menu_label is human-readable (perhaps even translatable!) text if
the MENU LABEL command is used, which isn't very convenient at the start of
a boot entry. Allow the entry to start with menu_ptr->label (an
identifier) as an alternative.
