Did they use build != host? That is where the problem is.

Makefile has:

            if [ "$(srcdir)" = "." ] ; then \
		...
              srcdiroption="--srcdir=."; \
              libsrcdir="."; \
            else \
              srcdiroption="--srcdir=$${topdir}/$${dir}"; \
              libsrcdir="$$s/$${dir}"; \
            fi; \
            if [ -f $${libsrcdir}/configure ] ; then \
              rm -f no-such-file skip-this-dir; \
              CONFIG_SITE=no-such-file $(SHELL) $${libsrcdir}/configure \

./configure is used if "$(srcdir)" == ".". Even if you use

# ../../libiberty/configure ...

it won't work since ../../libiberty has already been configured for the
target. You can't configure a different build directory when the source
directory has been configured already.
 
Please try build != host yourself to see what is going on. BTW, please
make sure you enable shared library.

Thanks.
