IBM made changes to no longer require 2 versions of libstdc++, so this
patch changes things back to the previous (compatible) way.

Also, TPF debuggers don't support discriminators, despite what GAS
supports, so disable them.

Ok?

	* config/s390/tpf.h (LIBSTDCXX): Change to CPP1.
	(LIB_SPEC): Add.
	(SUPPORTS_DISCRIMINATOR): Define.

But don't we need to support the older system (with 2 libstdc++s) andthe newer system (just one libstdc++)? Which implies these changes needto be conditional, right?


The SUPPORTS_DISCRIMINATOR change seems independent and is OK as-is.
