gcc/Makefile.in expects to find libiberty in ../libiberty if 
build==host.  Otherwise, it looks for it in ../$build/libiberty.  We 
can't use ../libiberty in this case because it was compiled for the 
host, not the build machine.

That seems reasonable, except this only works if we build the 
$build/libiberty directory.  This is supposed to happen via the toplevel 
configure.  If host_alias != build_alias, then it puts libiberty in 
build_modules.  It will then add a dependency
  maybe-all-build-libiberty: all-build-libiberty
to the Makefile.  Since all-gcc has a dependence on 
maybe-all-build-libiberty, this should force all-build-libiberty to be 
built.

At least, that is how it works in current sources, and gcc-3.4.  In 
gcc-3.3 it is a bit different, ALL_BUILD_MODULES gets set to 
all-build-libiberty.

Ah, I see the problem.  You didn't explicitly say what make command you 
used, but it is fairly obvious that you did
    make all-gcc
This won't work, because all-gcc does not depend on ALL_BUILD_MODULES. 
If you do
    make all
it will work.  Or alternatively, you can do
    make all-build-libiberty
    make all-gcc

In gcc-3.4, just "make all-gcc" will work fine.  Nathanael Nerode fixed 
this.  Explicitly adding "make all-build-libiberty" should work for any 
modern gcc version, so it should be OK to hard code that if it is simpler.
