Missing sysdeps/unix/sysv/linux/powerpc/powerpc64/libpthread-le.abilist, 
which also needs updating.

No, libpthread.a should only be considered in linknamespace testing for 
ISO11, not for ISO or ISO99.

Should also remove a blank line here instead of leaving two before #endif.

Are you sure it's safe to remove this empty GLIBC_2.22 section (present 
for the use of SHLIB_COMPAT calls, see nptl/pt-fork.c and commit 
beff1d132c16aedd87a3f1bc7b572c8e69819015)?
