The attached patch fixes the following warnings when building GRUB on
NetBSD (and probably other BSDs):

util/getroot.c: In function 'grub_make_system_path_relative_to_its_root':
util/getroot.c:2711:2: error: label 'parsedir' defined but not used
util/getroot.c: At top level:
util/getroot.c:1084:1: error: 'get_dm_uuid' defined but not used
util/getroot.c:1119:1: error: 'grub_util_get_dm_abstraction' defined but not 
used
