--disable-libiberty does not work (as I expect it)

Hi,

I'm trying to build arm-elf-gcc --with-sysroot. I succeeded to
build and install binutils before (worked out of the box) and now
I'm tring to get a C compiler.

If I did miss any documentation, any pointers appreciated!

Builds aborted with "Link tests are not allowed after
GCC_NO_EXECUTABLES" at some libdl (?) check. Some page in the
internet suggested --disable-shared, so I added it to the
configure options. Now building stops at:

  checking for library containing strerror... configure: error:
  Link tests are not allowed after GCC_NO_EXECUTABLES.
  make[1]: *** [configure-target-libiberty] Error 1
  make[1]: Leaving directory `/usr/local/build/gcc/gcc-4.6.0-arm'

If I understand correctly, it attempts to builb libiberty for my
target platform? I don't need it.

When I give `--disable-libiberty', I get an error earlier (that
is, there is no rule to make target ../libiberty/libiberty.a or
similar).

It seems to work when I configure with --enable-libiberty, make
until it aborts (as above), then configure in the same build dir
with --disable-libiberty and re-run make. Now the probably needed
../libiberty/libiberty.a is still there and used for linking, but
the no configure-target-libiberty executed and building works.

So I think I need libiberty for building the host gcc (called
the first and second stage compilers?), but not when building for
my target.

How do I do this correctly?
Any hints welcome!

Regards,
Steffen
