Error building linux-hosted compiler for solaris: "sed: option requires an argument"

[Hamilton Chris-cham <chris dot hamilton at freescale dot com>]

Hi,

I'm trying to build a gcc 3.4.1 cross-compiler that is hosted on i686-pc-linux and generates
binaries for sparc-sun-solaris2.8.  During the build, I'm new seeing errors involving "sed"
in the step that fixes up headers.

This is what I've done (all on the linux host):

INSTALL_PREFIX=/_TOOLS_/dist/gnu-gcc-3.4.1-binutils-2.15-sparc64-elf/i686-pc-linux2.4

1. Configure/build/install binutils:
    --prefix=$INSTALL_PREFIX
    --disable-nls
    --enable-64-bit-bfd
    --target=sparc64-elf

2. On Solaris machine, create tarball of /usr/include/* (recursive); then on linux
   box, unpack tarball to /home/cham/sparc-sun-solaris2.8-sys-include/usr/include

3. Configure/build gcc:
    --prefix=$INSTALL_PREFIX
    --with-headers=/home/cham/sparc-sun-solaris2.8-sys-include/usr/include
    --enable-threads
    --enable-shared
    --with-ld=${INSTALL_PREFIX}/bin/sparc64-elf-ld
    --with-as=${INSTALL_PREFIX}/bin/sparc64-elf-as
    --with-nm=${INSTALL_PREFIX}/bin/sparc64-elf-nm
    --enable-languages=c,c++
    --disable-nls
    --target=sparc64-elf

This is the result (truncated):

sed: option requires an argument -- e

Usage: sed [OPTION]... {script-only-if-no-other-script} [input-file]...

  -n, --quiet, --silent
                 suppress automatic printing of pattern space
  -e script, --expression=script
                 add the script to the commands to be executed
  -f script-file, --file=script-file
                 add the contents of script-file to the commands to be executed
      --help     display this help and exit
  -V, --version  output version information and exit

If no -e, --expression, -f, or --file option is given, then the first
non-option argument is taken as the sed script to interpret.  All
remaining arguments are names of input files; if no input files are
specified, then the standard input is read.

--------------------------------- OUTPUT ENDS ------------------------------------------

There are actually quite a few of these errors that occur back to back just before
the build attempt dies with the error exit.  Searching the digital hairball above for
'sed', I see the broken command embedded in the middle of a backquoted 'if' block:  

   "echo ar | sed -e    ;"
                     ^^
                     Shouldn't there be something useful here?

Can anyone help me figure out what I've done wrong?  Has anyone seen this kind of 
error before?   Is there a workaround?  

Desperate for a hint...
