No, that would be wrong. You always use the SONAME exactly because
an SONAME change means the library changed in an incompatible way.
The libopenal.so link is only used by the linker at compile time.
Therefore it's not availabe on a typical non-development
installation.

In this specific case ioquake3 can try libopenal.so.1 and fall back
to libopenal.so.0. Bad luck for versions that do not dlopen
libopenal but link directly, they will only work with one version of
openal.
