Looks like unconditional use of POWER8 transactional instructions [1].

The code should check for the availability of POWER8 or _CALL_ELF 2 before
trying to use POWER8 instructions:

(sid_ppc64el-dchroot)glaubitz@plummer:~$ echo | gcc -E -dM -|grep POWER
#define __POWER8_VECTOR__ 1
(sid_ppc64el-dchroot)glaubitz@plummer:~$ 
(sid_ppc64el-dchroot)glaubitz@plummer:~$ echo | gcc -E -dM -|grep ELF
#define __ELF__ 1
#define _CALL_ELF 2
(sid_ppc64el-dchroot)glaubitz@plummer:~$

Builds of powerpc and ppc64el work, this failure is only on ppc64.
This arch failed previously on Debian#1006527 but it was fixed on the
latest upload, and thus this second failure got uncovered.
