commit 256339712de21d7002129aed102b637cda634ab5
Author: Alexander Færøy <ahf at torproject.org>
AuthorDate: Fri Oct 14 12:12:46 2022 +0200

    Strip "__.SYMDEF*" before re-archiving in combine_libs on macOS and iOS.
    
    This patch changes how combine_libs works on Darwin like platforms to
    make sure we don't include any `__.SYMDEF` and `__.SYMDEF SORTED`
    symbols on the archive before we repack and run ${RANLIB} on the
    archive.
    
    See: tpo/core/tor#40683.
