TK1: Failed when building the crosstool-ng

I have installed autoconf-2.68 and configured crosstool-ng, and tried to build the crosstool.
But I meet a problem that I can’t build the crosstool successfully.

My ubuntu host version is Ubuntu 12.04 LTS
Linux ubuntu 3.2.0-23-generic-pae #36-Ubuntu SMP Tue Apr 10 22:19:09 UTC 2012 i686 i686 i386 GNU/Linux

feiying,
just to confirm you are building this for Jetson TK1 board and r21.5 BSP?

Hi feiying,

Any further information can be shared or this issue has been clarified and fixed?

Thanks
