I believe that these tests can already be skipped:

  I made some change such that a test is skipped if it requires recoded
  file names and file names recoding failed.

ChangeLog entry:

2022-03-10  Patrice Dumas  <pertusus@free.fr>

        * tp/tests/Makefile.am (input_file_names_recoded_stamp.txt):
        record in the file if the recoding succeeded or failed.

        * tp/tests/run_parser_all.sh: if 'Need recoded file names'
        appears on a test line, skip the test if the recoding of
        file names failed.

        * tp/tests/run_parser_all.sh: if a prerequisite for a test is
        missing, such as not recoded file names needed, or latex2html
        or tex4ht not present, and only one test is run, return 77 to
        have the test marked as skipped instead of succeeding.


With your setup, it breaks at the very beginning, in the Makefile
rule.  It would seem to be simple to eliminate the reference to
"included_latîn1.texi" from the Makefile.  Then we have to make
sure the tests are skipped.
