Comment 1

[Mike Hommey [:glandium]]

Attachment: Bug 1849049 - Don't try to export non-existing symbols.

On e.g. Linux x86, ffvpx is built for audio only, and doesn't contain
some of the new symbols added in bug 1823953. In turn, with clang-trunk
(lld trunk, really), this leads to a hard error because lld is now less
lenient about the symbols listed in version scripts: they have to exist.
