Panu Matilainen aec1fe6fe8 mk: add DT_SONAME to shared libraries
This is all-important now that the libraries are versioned: DT_SONAME
presence instructs the runtime dynamic linker to load the shared object
by the versioned name in DT_SONAME instead of the the unversioned symlink
name used during build.
