Purge cruft now we have build libiberty.
* Makefile.in (OBSTACK, VFPRINTF, DOPRINT, STRSTR,
HOST_OBSTACK, HOST_VFPRINTF, HOST_DOPRINT, HOST_STRSTR,
USE_HOST_OBSTACK, USE_HOST_VFPRINTF, USE_HOST_DOPRINT,
USE_HOST_STRSTR): Delete variables.
(vfprintf.o, doprint.o, strstr.o, splay-tree.o, obstack.o,
hashtab.o, safe-ctype.o, $(HOST_PREFIX_1)obstack.o,
$(HOST_PREFIX_1)vfprintf.o, $(HOST_PREFIX_1)doprint.o,
$(HOST_PREFIX_1)strstr.o), $(HOST_PREFIX_1)): Delete rules.
(LIBIBERTY, BUILD_LIBIBERTY): New variables.
(LIBDEPS): Now just $(INTLDEPS) $(LIBIBERTY).
(LIBS): Now just $(INTLLIBS) @LIBS@ $(LIBIBERTY).
(HOST_LIBDEPS): Now just $(BUILD_LIBIBERTY).
(HOST_LIBS): Ditto.
(HOST_RTL): Remove hashtab.o safe-ctype.o.
(OBJS): Remove splay-tree.o.
(gen-protos): Depend on $(HOST_LIBS), not ../libiberty/libiberty.a.
(distclean): No need to delete splay-tree.c obstack.c
hashtab.c safe-ctype.c.
(mostlyclean): Delete build copies of print-rtl.c bitmap.c
errors.c ggc-none.c (all prefixed with $(HOST_PREFIX_1).
* aclocal.m4 (gcc_AC_FUNC_VFPRINTF_DOPRNT, gcc_AC_FUNC_STRSTR):
Delete.
* configure.in: Don't use them.
Set and substitute @FORBUILD@.
* config.in, configure: Regenerate.
* doprint.c: Move to libiberty/_doprnt.c.
* doc/configterms.texi: Document that libiberty is now built
up to three times. Fix typo.
* f/Make-lang.in (f/fini, f/intdoc): Depend on $(HOST_LIBDEPS)
and link with $(HOST_LIBS), not safe-ctype.o.
