You're using a multi-OS directory, so you need to put them where GCC
will expect OS directories.  It won't use the OS libdir suffix for
<target>/lib.

Try this instead:
  Add --with-sysroot=/opt/sparctools/sys-root
  32-bit files in <prefix>/sys-root/usr/lib
  64-bit files in <prefix>/sys-root/usr/lib64
  System headers in <prefix>/sys-root/usr/include

I assume you're using 3.4, by the way.
