But what *does* it do? I mean, the Makefile comment
notes:

# This target exists so that everything can be made in one pass.
# 'all-gcc' has to avoid stomping on the bootstrap-generated gcc for
# this to work.

but that isn't terribly useful.

There is also the relatively new configure flag:

  --enable-intermodule    build the compiler in one step

which looks the same (is it?).

The "spectacular failures" were coming because the test
scripts were executing just "gcj" instead of the just
build gcj - on my box, the vendor installed GCJ is 3.2.3,
which was indeed quite lacking and hence the results.

I have uninstalled that GCJ and now the testsuite fails
to execute:
===========================================================
[...]
Running /home/ranmath/src/gcc/gcc-20040408/libjava/testsuite/libjava.cni/cni.exp
 ...
couldn't execute "gcj": no such file or directory
    while executing
"exec gcj -B/home/ranmath/src/gcc/build/i686-pc-linux-gnu/libjava/testsuite/../
-v 2>@ stdout"
[...]
===========================================================

I note that "GCJ" is being correctly set in
the generated Makefile for the testsuite, but for some
reason it is not picking it up. (It should, if I go by
"libjava/testsuite/lib/libjava.exp".)

But how does it work for "normal" bootstrap then?
