Makefile: build dylib on macOS

Browse Source 
On macOS, shared libraries end in "$(SOVERSION).dylib", not
".so.$(SOVERSION)" like on Linux.  Also, a different linker option is
needed to set the equivalent of the soname.

This is based on patches from:

	Elmar Pruesse <elmar.pruesse@ucdenver.edu>
and
	Roy Storey <kiwiroy@users.noreply.github.com>

but refactored, and fixed to not break the Windows build.
