issues: dynstr_section_longer_by_two_bytes_which_are_NULs: Add some observations.

  description: |

    The .dynstr section on the right build is longer by two bytes.

    The value of those two bytes is 0x00 0x00.

    .

    stlink=1.7.0+ds-1 is currently in both bullseye and sid; is reproducible on

    the former but not on the latter; and has this issue.  The issue could be

    caused by a difference in some build dependency between the two suites (for

    some common build dependency of all packages having this issue); or by

    a difference in the variations tested in the two suites.

    .

    The only difference in variations (per current "Variations tested" page) is

    the build path variation.

    .

    So, is there any any chance that this issue is caused by the build path

    variation?  <wild speculation>Perhaps the number of extra bytes is 2

    because the build path in build #2 is two bytes longer than in build

    #1?</wild speculation>
