You must set any, necessary, environment variables before executing the
configure script.  How you set the environment variables depends on your
shell.  In an sh(1)-like shell, you might do something like the
following:

    FC= ./configure >configure.log 2>&1

whereas, in a csh(1)-like shell, you might do the following:

    setenv FC ""
    ./configure >configure.log

Would you please send me the entire output from executing the configure
script.

I believe that the problem you're encountering is related to the
following error messages from the file "config.log":

    configure:2084: cc -o conftest -O -DNDEBUG  conftest.c -lc   1>&5
    ld: /usr/lib/crti.o: Relocation R_PPC_LOCAL24PC is not yet supported for 
symbol _GLOBAL_OFFSET_TABLE_.
    ld: /usr/lib/crti.o: Relocation R_PPC_PLTREL24 is not yet supported for 
symbol __gmon_start__.
    ld: final link failed: Invalid operation

I suspect that your development environment (i.e. your compilation and
linking environment) is corrupt somehow.  Try the following:

    1.  Go to the top-level source directory.

    2.  Create the file "conftest.c" with the following contents:

            #line 2327 "configure"
            #include "confdefs.h"
            main(){return(0);}

        Left-justify all the above lines in the file.  The above is from
        the cross-compilation test in the configure script.

    3.  Build the above with the following command:

            cc -o conftest -O -DNDEBUG conftest.c

        If the file won't compile because of the "#include "confdefs.h"
        line, then remove that line and try again.

    4.  If the above build fails, then show the output to your system
        manager.  I'd also like to see the output.
