	* gcc-interface/Makefile.in, gcc-interface/Make-lang.in:
	Remove obsolete targets referencing gen-soccon
	When generating s-oscons.ads, use a file name that includes the
	THREAD_KIND, to ensure that the (potentially different) version from a
	previous build with a different threads flavour does not get reused.
