makedumpfile-1.2.2: Fix the problem that vmcoreinfo cannot be extracted from ELF32 /proc/vmcore

[Ken'ichi Ohmichi]

Hi,

makedumpfile version 1.2.2 is released.
Please test it. Your opinions/comments are welcome.

Explanation of makedumpfile:
  To shorten the size of the dumpfile and the time of creating the
  dumpfile, makedumpfile copies only the necessary pages for analysis
  to the dumpfile from /proc/vmcore. You can specify the kind of
  unnecessary pages with dump_level. If you want to shorten the size
  further, enable the compression of the page data.

Changelog:
o Fix the problem that vmcoreinfo cannot be extracted from ELF32 /proc/vmcore.
  There was a problem that makedumpfile cannot extract vmcoreinfo from
  an ELF32 /proc/vmcore:
    # makedumpfile -cd31 /proc/vmcore dumpfile
    get_pt_note_info: Can't find PT_NOTE Phdr.
    
    makedumpfile Failed.
    #
  The cause was that makedumpfile checked the address of flag_elf64 instead of
  the value.
