still struggling with toolchain

Hi,

I tried to build my toolchain following this thread

previous thread (http://forum.niosforum.com/forum/index.php?showtopic=3129&st=0)

and I did the best I could. But somehow I am still stuck at the busybox.

/home/bdu/NIOS/buildroot/build_nios2/staging_dir/bin-ccache/../lib/gcc/nios2-linux-uclibc/3.4.2/../../../../nios2-linux-uclibc/bin/ld: unrecognized option '-z'

/home/bdu/NIOS/buildroot/build_nios2/staging_dir/bin-ccache/../lib/gcc/nios2-linux-uclibc/3.4.2/../../../../nios2-linux-uclibc/bin/ld: use the --help option for usage information

GNU ld version 2.15

collect2: ld returned 1 exit status

make[2]: *** [libbusybox.so.1.1.1] Error 1

make[1]: *** [_all] Error 2

make[1]: Leaving directory `/home/bdu/NIOS/buildroot/build_nios2/busybox'

make: *** [/home/bdu/NIOS/buildroot/build_nios2/busybox/busybox] Error 2

The ld does not support -z option. I guess this has something to do with the patches or configs. But I could figure out which part I missed.

I'd appreciate any help on this.
