Gets further:

make[2]: *** No rule to make target `-L/opt/gnu/hidden/lib', needed by `tree1'. 

It seems treelang/Make-lang.in has a dependency on various backend libraries:
# back end compiler libraries etc
TREE_BE_LIBS = $(BACKEND) $(LIBIBERTY) $(INTLIBS) $(LIBS) $(LIBDEPS)

and we have

# core compiler
tree1$(exeext): treelang/tree1.o treelang/treetree.o treelang/tree-convert.o \
	treelang/lex.o treelang/parse.o \
	$(TREE_BE_LIBS) attribs.o

The gcc Makefile includes LIBINTL in LIBS.  Configure set LIBINTL to:

# Internationalization library.
LIBINTL = /opt/gnu/lib/libintl.sl -L/opt/gnu/hidden/lib /opt/gnu/hidden/lib/libiconv.sl -lc -Wl,+b -Wl,/opt/gnu/hidden/lib

I'll try removing the dependency of tree1 on TREE_BE_LIBS.
