This works for me on powerpc64-linux-gnu configured as such:
--prefix=${HOME}/gcc-mainline --with-mpfr=/usr/local --with-cpu=default32

The only thing I can think of which is causing the issue is that the
check for pthread_setaffinity_np is defining _GNU_SOURCE but
config/linux/affinity.c is not but I just looked into the source and
it does:
#ifndef _GNU_SOURCE
#define _GNU_SOURCE 1
#endif


So I don't think that is the issue.  Can you look into config.log and
make sure that the test is not emitting warnings.  It is a link time
test too.  The other problem might be that you have an older
pthreads.h header file installed and a newer libpthreads.so so the
versions are mismatching.
