BFD_VMA_FMT doesn't always work with long long. llx has been used:

dwarf.c:  snprintf (buff, sizeof (buff), "%16.16llx ", val);
nm.c:static char value_format_64bit[] = "%016llx";
prdbg.c:	sprintf (buf, "0x%llx", (unsigned long long) vma);
readelf.c:		  ? "%16.16llx  %16.16llx "
readelf.c:		  : "%12.12llx  %12.12llx ",
strings.c:	        printf ("%7llx ", (unsigned long long) start);

print_vma will fail many tests due to leading 0s.
