There is the problem because it's not happening.

Yes, Solaris.

It's SharedLibraryTarget that is used, Concat is just part of the
definition.  And no, we don't want to change it either, but it's not
doing what we want so it needs a new SharedLibraryTarget macro in
the template.

That now uses the libaudio.so.2 as the SONAME but also calls the library
that too.  So there is no version to label the file.

Obviously what we want is the real file called .so.2.4, links from
.so.2 and .so to .so.2.4 and the SONAME to be .so.2.

Can imake do it?  I don't know.  I know I can post configure modify
easily.  One edit and one extra link.  <rant>Porting "OS independent"

A crutch link from .so.2.3 to .so.2.4 will save relinking dependents.
