So, it is on the libtool command-line but libtool removes it from the
linker commands? How about adding it to this section in
config/ltmain.m4sh? Might as well group them.
      # -64, -mips[0-9] enable 64-bit mode on the SGI compiler
      # -xarch=*, -xtarget=* enable 64-bit mode on the Sun compiler
      # +DA*, +DD* enable 64-bit mode on the HP compiler
      # -q* pass through compiler args for the IBM compiler
      # -m* pass through architecture-specific compiler args for GCC
      -64|-mips[[0-9]]|-xarch=*|-xtarget=*|+DA*|+DD*|-q*|-m*)
        arg=`$ECHO "X$arg" | $Xsed -e "$sed_quote_subst"`
        func_quote_for_eval "$arg"
        arg="$func_quote_for_eval_result"
        compile_command="$compile_command $arg"
        finalize_command="$finalize_command $arg"
        compiler_flags="$compiler_flags $arg"
        continue
        ;;
