    Fix read_ranges for 32-bit long
    
    bfd/dwarf2.c:read_ranges compares bfd_vma values against -1UL, which
    doesn't work correctly when long is 32-bit and bfd_vma is 64-bit
    (observed as "nm -l" being very slow for mingw64 host; probably causes
    issues on 32-bit hosts as well as IL32LLP64 cases such as mingw64).
    Fix by using (bfd_vma) -1 in place of -1UL, as done elsewhere.
