m68k/mvme162 build problem on solaris-7

I'm having trouble building RTEMS for a m68k-rtems target and a mvme162 
bsp;  something I thought would be
pretty stable.
My configure scipt is attached;  The important part is:

      export   CC_FOR_BUILD=/tools/local/bin/gcc
      export  CXX_FOR_BUILD=/tools/local/bin/g++
      export    CC_FOR_HOST=/tools/local/bin/gcc
      export   CXX_FOR_HOST=/tools/local/bin/g++
      export  CC_FOR_TARGET=/tools/local.m68k-elf/bin/m68k-elf-gcc
      export CXX_FOR_TARGET=/tools/local.m68k-elf/bin/m68k-elf-g++
      ${SHELL}  ${SRCDIR}/configure                                 \
            --prefix=$LOCAL                                         \
            --target=m68k-rtems                                     \
            --program-prefix=m68k-elf-                              \
            --disable-rtems-inlines                                 \
            --disable-posix                                         \
            --disable-networking                                    \
            --disable-cxx                                           \
            --enable-rtemsbsp="mvme162"                             \


    rtems> /tools/local/bin/gcc --version

This is my old reliable gcc for solaris

    rtems> /tools/local.m68k-elf/bin/m68k-elf-gcc --version
    m68k-elf-gcc (GCC) 3.4.0 20031224 (experimental)

    This is free software; see the source for copying conditions.  There
    is NO

The above is a new m68k gcc cross compiler that seems to work (judged by 
looking at the assembly code)

The error I see during the rtems build is:

Line-810 invokes a 'configure' that seems to be using my m68k-cross 
compiler as if it were the solaris compiler.
I have verified that it compiles a small program (below) with the m68k 
compiler and then  dies when it can't
run the m68k binary on Solaris (so suprize there):

    #line 2225 "configure"
    /* confdefs.h.  */

    #define PACKAGE_NAME "rtems-c-src-lib-libbsp-m68k-mvme162-tools"
    #define PACKAGE_TARNAME "rtems-c-src-lib-libbsp-m68k-mvme162-tools"
    #define PACKAGE_VERSION "4.6.0pre5"
    #define PACKAGE_STRING "rtems-c-src-lib-libbsp-m68k-mvme162-tools
    #define PACKAGE_BUGREPORT "rtems-bugs at rtems.com"
    /* end confdefs.h.  */

    main ()

      return 0;

I could use some advice.
Thanks much.
