Subject: [PATCH] Fix building of gengtype

Found bootstrap failures even with this patch (dunno what changed on my box
that I started getting these last night, make has not changed), that time
with errors.o and gcc-ar.o.
The generated headers are solved these days in automatic dependencies world
through
# In order for parallel make to really start compiling the expensive
# objects from $(OBJS) as early as possible, build all their
# prerequisites strictly before all objects.
$(ALL_HOST_OBJS) : | $(generated_files)
and build/*.o have explicit dependencies.
I've tried to compare $(ALL_HOST_OBJS) on my box with all *.o */*.o files
I had in stage3 directory, and besides build/*.o, I found:

crtbegin.o crtbeginS.o crtbeginT.o crtend.o crtendS.o crtfastmath.o crtprec32.o crtprec64.o crtprec80.o
errors.o gcc-ar.o gcc-nm.o gcc-ranlib.o gengtype-lex.o gengtype.o gengtype-parse.o gengtype-state.o

not being listed in ALL_HOST_OBJS.  The crt*.o files come from libgcc build
and thus are ok, the rest I've tried to handle in the following updated
patch.  If the #define GENERATOR_FILE inside of the 5 files is too ugly,
another alternative might be to define both -DHOST_GENERATOR_FILE -DGENERATOR_FILE
in Makefile.in and don't error in config.h if GENERATOR_FILE is defined,
if HOST_GENERATOR_FILE is also defined.

2014-12-03  Jakub Jelinek  <jakub@××××××.com>

	* Makefile.in (ALL_HOST_BACKEND_OBJS): Add $(GENGTYPE_OBJS),
	gcc-ar.o, gcc-nm.o and gcc-ranlib.o.
	(GENGTYPE_OBJS): New.
	(gengtype-lex.o, gengtype-parse.o, gengtype-state.o, gengtype.o):
	Remove explicit dependencies.
	(CFLAGS-gengtype-lex.o, CFLAGS-gengtype-parse.o,
	CFLAGS-gengtype-state.o, CFLAGS-gengtype.o): Add -DHOST_GENERATOR_FILE
	instead of -DGENERATOR_FILE.
	(CFLAGS-errors.o): New.
	* gengtype.c: Instead of testing GENERATOR_FILE define, test
	HOST_GENERATOR_FILE.  If defined, include config.h and define
	GENERATOR_FILE afterwards, otherwise include bconfig.h.
	* gengtype-parse.c: Likewise.
	* gengtype-state.c: Likewise.
	* gengtype-lex.l: Likewise.
	* errors.c: Likewise.
