[BUG] Org publish makeindex doesn't work on symlinked path [9.6.4 ( @ /home/bence/src/org-mode/lisp/)]

[Bence Fábián]

Hi,

When performing an `org-publish' if the `:base-directory' property
contians a symlink in its path, then the `theindex.inc' file is not
populated.

I created a repo to help reproduce the bug:
https://github.com/bencef/org-publish-symlink-repro

Please see version information below.

Best Regards,
Bence
