Define GENERATOR_FILE explicitly for the host gengtype objects

Hello,

Since r177358, a host executable gengtype is built so that plugins can
use the GTY markers.

Even for the host, gengtype is a GENERATOR_FILE, but since the build-%
rule doesn't apply to host objects, gengtype was being built without
it. So when I removed coretypes.h from double-int.h, my build failed.

Fixed by adding -DGENERATOR_FILE explicitly to the host gengtype*.o objects.

Bootstrapped on powerpc64-unknown-linux-gnu. OK for trunk?

Ciao!
Steven

	* Makefile.in (gengtype-lex.o, gengtype-parse.o, gengtype-state.o,
	gengtype.o): Add -DGENERATOR_FILE manually for host gengtype objects.

Ok!

I hope that with the C++ gengtype restructuring it will be no longer necessary
to build a host gengtype.
