shlib-build: Add -p option

Add a -p option to shlib-build option to generate "plain" shared
objects. That is, shared objects that are intended to be e.g.
dlopen()'d, and are not intended to be libraries dynamically linked to
from other code. Such shared objects do not need a library name,
version numbers, export lists, etc.
