	* mlib-tgt-darwin.adb (Build_Dynamic_Library): Remove the "-fini"
	switch, not supported by the linker on Darwin. Add '_' before
	<library>init, as this character is added unconditionally by the
	compiler.
	(Is_Archive_Ext): Replace the wrong library extension ".dyld" by the
	correct one ".dylib". This fixes detection of the archive files when
	building library projects.
