allow setting soname without suffix or prefix

Allows to create a library with a different
SONAME without the need to add suffixes to symbols
Backwards compatible and should have no effect
on the workflow and previous users.
Useful for allowing INTERFACE64 library alongside
the standard library without file conflicts
