This allows user to build FFmpeg against Intel oneVPL. oneVPL 2.6
is the required minimum version when building Intel oneVPL code.
It will fail to run configure script if both libmfx and libvpl are

Yes, making everything except for av_ hidden by default would be more
consistent with the current build process, which includes libavcodec.v.
Though, this is a special case that results not only in increasing the
shared object file size if libavcodec.v is not used, which is
undesirable, yet har

The AArch64 assembly accesses those symbols directly, without
indirection via e.g. the GOT on ELF. In order for this not to
require text relocations, those symbols need to be resolved fully
at link time, i.e. those symbols can't be interposable.
