This version should already have the build-id support.

Explicit `symbol-file' command will load it as it can load arbitrary file for
the symbols.  Automatic finding of the associated separate debug info files
(find_separate_debug_file) ignores any files with non-matching build-id or
CRC32.

Yes, I think your mail has nothing to do with build-id.

In the Bug it is shown libc has correct CRC32 but libcairo does not.
