Ryan is on vacation and he asked to answer the question that may arise for 2.16 release. And
I too believe his "no new regressions" means "No new regressions versus a baseline of 
failures from 2.15." since in my PPC32 and PPC64 for POWER4 tests I do see the 'check-abi-libc'
errors with the following difference:

- _mcount F
- _nl_default_dirname D 0x12
+ _nl_default_dirname D 0xf


Besides that I do saw the 'rt/tst-cpuclock2' intermittent failures which afaik is due a kernel
issue (I'm testing on an old 2.6.32). For POWER7 PPC32 I also see the 
'stdlib/tst-setcontext', 'stdlib/tst-makecontext3', and 'tst-setcontext-fpscr' which are all
known kernel issues.

My tests were done on Linux 2.6.32, GCC 4.6.4, Binutils 2.22.52.
