In #7985, the
linkcheck
builder has been extended to also check local links.However, the local file URIs are checked relative to the global source directory.
If a relative path is used in a source file in a sub-directory, the file is not found and a linkcheck error is reported.
This PR uses the actual source directory of the current source file.
