It seems that now some official package builds are affected by this.
Just in case, this is the same kind of issue as discussed at length in
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=285401
Multiple ports had to be (individually) patched for it.

Preamble: I made this change a while ago but couldn't find time to share it.
Now I see that ffmpeg 8 is in the works, so maybe I am too late or, at least,
the change will need some rework.
The change addresses an issue similar to https://bugs.freebsd.org/bugzilla/
show_bug.cgi?id=284651 and multiple others.

multimedia/ffmpeg: fix symbol versioning problem on stable/14
This is a well-known issue related to visibility of environ and __progname
symbols from /usr/lib/crt1.o.
This change patches configure to give those symbols global visibility
when testing --version-script support.
Otherwise, the port would produce broken libraries without symbol versions.
This change also adds HAS_SYMBOL_VERSION to catch the problem using
libavcodec.so as a canary.
