Bug#918667: libopenal-dev on kFreeBSD: missing dependency libsndio?

[Коля Гурьев]

Package: libopenal-dev
Version: 1:1.19.1-1
Control: affects -1 telegram-desktop

I try to build a simple example[1] found on the world wide web. It
requires libalut or libaudio. And it uses no any header or function of
libsndio, but I get the following error.

    cc openal-example.o -o openal-example -lopenal -lalut
    /usr/bin/ld: warning: libsndio.so, needed by /usr/lib/gcc/i686-kfreebsd-gnu/6/../../../i386-kfreebsd-gnu/libopenal.so, not found (try using -rpath or -rpath-link)

The issue affects also telegram-desktop on kfreebsd-amd64[2].
