Makefile bug

[Andreas Schwab]

Building the demangler program requires a working target compiler (to
create underscore.c), thus it cannot be built in a canadian cross.

	* Make-lang.in (c++.all.build): Don't depend on $(DEMANGLER_PROG),
	which requires a working target compiler to build.

Makefile bug

[Andreas Schwab]

The rule for genrtl.[ch] needs to have a dummy command, otherwise GNU make
won't recheck the modification time of the targets after remaking
stamp-genrtl and won't notice when they change.
