Solaris10 for 64bits test

[jianhao]

We want to compile 64bits cppunit on Solaris10 using CC5.8 in our X86 computer. Following is the configure command line:
./configure CXX=CC CXXFLAGS="-pta -instances=static -mt -xarch=amd64 -g -features=no%transitions -xildoff" LD=CC LDFLAGS="-xildoff -L/opt/SUNWspro/lib/amd64 -64" CC=CC

and then make it. at the last of make process, errors ocures.

ld: 致命的: 文件 .libs/AdditionalMessage.o：错误的 ELF 类型：ELFCLASS64
ld: 致命的: 文件处理错误。无输出写到.libs/libcppunit-1.12.so.0.0.0

The following command caused the error:

done; \

  echo "Making $target in $subdir"; \
  if test "$subdir" = "."; then \
    dot_seen=yes; \
    local_target="$target-am"; \
  else \
    local_target="$target"; \
  fi; \
  (cd $subdir && make  $local_target) \
  || eval $failcom; \
done; \
if test "$dot_seen" = "no"; then \
  make  "$target-am" || exit 1; \
fi; test -z "$fail"

I want to know how can I finish it.
