<sigh>  I must need some time off. :)

Did it and learned that you are right.  gcc/configure is not finding the
gas/configure.in because of the way it is following the symlinks.   I have
a tree symlinked like the one-tree script does.  Here is enough of the
link stuff to show what is happening.

      rm -rf src
      mkdir src
      cd src
      for f in gcc libio libstdc++ texinfo xiberty
      do
          ln -s ../${GCC}/${f} . 
      done
      for f in bfd binutils gas gprof ld opcodes etc
      do
           ln -s ../${BINUTILS}/$f .
      done
      ln -s ../${NEWLIB}/newlib .

So when you are in build/gcc:

$ ls -l ../../src/gcc
lrwxrwxrwx   1 joel     users          20 Jul 14 10:51 ../../src/gcc ->
../egcs-19980628/gcc
ls -l ../../src/gas
lrwxrwxrwx   1 joel     users          21 Jul 14 10:51 ../../src/gas ->
../binutils-2.9.1/gas

But ... somehow the symlinks do not get followed as one would like.
Watch this:

$ pwd
/usr1/rtems/work/tools/b/gcc
$ cd ../../src/gcc/../gas
$ pwd
/usr1/rtems/work/tools/src/gas
$ cd -
$ pwd
/usr1/rtems/work/tools/b/gcc
$ ls -l ../../src/gcc/../gas
ls: ../../src/gcc/../gas: No such file or directory

I am not a symlink expert but it looks like it is not being followed as
expected.
