[jimwang118]

Fix the following error.

/usr/bin/ld: /mnt/vcpkg/installed/x64-linux/debug/lib/pkgconfig/../../lib/libsndfile.a(g72x.c.o): in function `step_size':
/mnt/vcpkg/buildtrees/libsndfile/src/1.2.2-fa730f3d73.clean/src/G72x/g72x.c:299: multiple definition of `step_size'; subprojects/gst-plugins-bad/gst/siren/libgstsiren.a(common.c.o):/mnt/vcpkg/buildtrees/gstreamer/x64-linux-dbg/../src/1.24.7-08ef53880b/subprojects/gst-plugins-bad/gst/siren/common.c:47: first defined here

• Changes comply with the maintainer guide.
• SHA512s are updated for each updated download.
• The "supports" clause reflects platforms that may be fixed by this new version.
• Any fixed CI baseline entries are removed from that file.
• Any patches that are no longer applied are deleted from the port's directory.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Only one version is added to each modified port's versions file.

The feature sndfile test passed with x64-linux and x64-windows triplets.

This looks like something that should be committed upstream. Has upstream been notified?

I submitted issue 3761 upstream but have not received a response.
