The standard location of dictionary.txt is under codespell's package, on
my machine atm (codespell 2.1, Artix Linux):
/usr/lib/python3.9/site-packages/codespell_lib/data/dictionary.txt

Since we enable the codespell by default for SOF I have constant:
No codespell typos will be found - \
file '/usr/share/codespell/dictionary.txt': No such file or directory

The patch proposes to try to fix up the path following the recommendation
found here:
https://github.com/codespell-project/codespell/issues/1540

Hi,

Changes since v3:
- Do not try to override the use provided codespell file location

Changes since v2:
- Only try to check for dictionary path it is enabled or when the help is
  displayed
 - Move the check after the GetOptions()
 - Set $help to 2 in case invalid option is passed in order to be able to use
   correct exitcode and still display the correct path for dictionary.txt

Changes sicne v1:
- add missing ';' to the line updating the $codespellfile with $codespell_dict

Regards,
Peter

This is really hard to read.

Can this be written something like

my $python_codespell_dict = << "EOF"
import os.path as op
import codespell_lib
codespell_dir = op.dirname(codespell_lib.__file__)
codespell_file = op.join(codespell_dir, 'data', 'dictionary.txt')
print(codespell_file)
EOF
;
my $codespell_dict = `python3 -c "$python_codespell_dict" 2> /dev/null`;

Yes, this definitely looks much better, thanks for the suggestion!
